Subject: [PATCH 002/425] rcu: Clean up code based on review feedback from Josh
Triplett
These issues identified during an old-fashioned face-to-face code
review extended over many hours.
o Bury various forms of the "rsp->completed == rsp->gpnum"
comparison into an rcu_gp_in_progress() function, which has
the beneficial side-effect of forcing consistent use of
ACCESS_ONCE().
o Replace hand-coded arithmetic with DIV_ROUND_UP().
o Bury several "!list_empty(&rnp->blocked_tasks[rnp->gpnum & 0x01])"
instances into an rcu_preempted_readers() function, as this
expression indicates that there are no readers blocked
within RCU read-side critical sections blocking the current
grace period. (Though there might well be similar readers
blocking the next grace period.)
o Remove a dangling rcu_restart_cpu() declaration that has
been dangling for almost 20 minor releases of the kernel.

Subject: [PATCH 003/425] rcu: Clean up code based on review feedback from Josh
Triplett, part 2
These issues identified during an old-fashioned face-to-face code
review extending over many hours.
o Add comments for tricky parts of code, and correct comments
that have passed their sell-by date.
o Get rid of the vestiges of rcu_init_sched(), which is no
longer needed now that PREEMPT_RCU is gone.
o Move the #include of rcutree_plugin.h to the end of
rcutree.c, which means that, rather than having a random
collection of forward declarations, the new set of forward
declarations document the set of plugins. The new home for
this #include also allows __rcu_init_preempt() to move into
rcutree_plugin.h.
o Fix rcu_preempt_check_callbacks() to be static.

Subject: [PATCH 010/425] parisc: tracehook_report_syscall
This makes parisc use the standard tracehook_report_syscall_entry
and tracehook_report_syscall_exit hooks in <linux/tracehook.h>.
To do this, we need to access current->thread.regs, and to know
whether we're entering or exiting the syscall, so add this to
syscall_trace.

Subject: [PATCH 014/425] parisc: stop using task->ptrace for
{single,block}step flags
task->ptrace flags belong to generic code, so instead thief some
TIF_ bits to use. Somewhat risky conversion of code to test TASK_FLAGS
instead of TASK_PTRACE in assembly, but it looks alright in the end.

Subject: [PATCH 019/425] parisc: rename parisc's vmalloc_start to
parisc_vmalloc_start
building kernel 2.6.32(pre), gives this compiler warning:
/linus-linux-2.6/mm/vmalloc.c: In function 'pcpu_get_vm_areas':
/linus-linux-2.6/mm/vmalloc.c:2104: warning: 'vmalloc_start' is used
uninitialized in this function
The reason is, that the code in mm/vmalloc defines a local variable called
vmalloc_start, which is already defined as global variable in parisc's code.
To avoid this kind of problems in future, I suggest to rename the parisc
variable
to parisc_vmalloc_start.

Subject: [PATCH 025/425] sh: Handle ioport_map() cases for >= P1SEG addresses.
This fixes up the case where certain drivers already do their own
remapping and subsequently attempt to use the PIO calls for I/O. In this
case there is no additional remapping that needs to be done, and the
address can be casted in to the cookie directly.

Subject: [PATCH 026/425] sh: Set the default I/O port base to P2SEG.
This bumps up the default I/O base to P2SEG, which allows legacy probing
to bail out gracefully rather than oopsing. Platforms that have a real
PIO offset still need to fix this up on their own, although most
platforms are content with P2SEG already.
The previous change to teach ioport_map() about >= P1SEG offsets in
combination with this patch allows both the already remapped and the
legacy address probing to pass through and succeed.
Fixes up an oops with i8042 on the sh7785lcr board.

Since we now use the embedding percpu allocator we have to make the

Besides some minor asm adjustments, this turned out to be pretty
trivial.

intel_crtc_cursor_set
Commit 74dff282 exposed this unnecessary call by causing a change in
the failure path on i965 where framebuffer compression will be turned
on and off on every cursor update. If you don't have the xf86-video-intel
fix to avoid the blinking cursor effect, this is very slow.
Symptoms were a far more noticeable cursor blink with every cursor image
change combined with severe slowdown for animated cursors.

Subject: [PATCH 034/425] drm/i915: batch submit seqno off-by-one.
We increment the seqno number between submitting the batch buffer and
the flush/interrupt that demarcates its end, so the tracepoint needs to
reference the incremented value to match the completion event.

Subject: [PATCH 035/425] drm/i915: Enable irq to trace batch buffer
completion.
If we trigger a tracepoint for batch buffer submission, it is a reasonable
assumption that we wish to also trace the batch buffer completion. So in
order to capture the completion events, we need to enable irqs... However,
we cannot rely on the completion event to disable the irq later, so we
defer the irq disable to the retire request.

Subject: [PATCH 043/425] sh: Disable unaligned kernel access printks by
default.
Certain networking and USB workloads generate floods of these accesses,
so just disable it by default (thereby restoring the old behaviour). The
option remains configurable from userspace, and can still be used as a
debugging aid.

Subject: [PATCH 046/425] x86: Optimize cmpxchg64() at build-time some more
Try to avoid the 'alternates()' code when we can statically
determine that cmpxchg8b is fine. We already have that
CONFIG_x86_CMPXCHG64 (enabled by PAE support), and we could easily
also enable it for some of the CPU cases.
Note, this patch only adds CMPXCHG8B for the obvious Intel CPU's,
not for others. (There was something really messy about cmpxchg8b
and clone CPU's, so if you enable it on other CPUs later, do it
carefully.)
If we avoid that asm-alternative thing when we can assume the
instruction exists, we'll generate less support crud, and we'll
avoid the whole issue with that extra 'nop' for padding instruction
sizes etc.

Just like ip_fast_csum, the assembly snippet in csum_ipv6_magic needs a
memory clobber, as it is only passed the address of the buffer, not a
memory reference to the buffer itself.
This caused failures in Hurd's pfinetv4 when we tried to compile it with
gcc-4.3 (bogus checksums).

Subject: [PATCH 048/425] tracing: Fix infinite recursion in
ftrace_update_pid_func()
When CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST is enabled
__ftrace_trace_function contains the current trace function, not
ftrace_trace_function.
In ftrace_update_pid_func() we currently incorrectly assign the
value of ftrace_trace_function to __ftrace_trace_funcion before
returning.
Without this patch it is possible to execute an infinite recursion
whereby ftrace_test_stop_func() calls __ftrace_trace_function,
which was assigned ftrace_test_stop_func() in
ftrace_update_pid_func().

Subject: [PATCH 050/425] perf timechart: Add a power-only mode
For doing work on the Linux power management components, I need to
make long (30+ seconds) traces. Currently, this then results in a
HUGE svg file, with mostly process data that isn't interesting.
This patch adds a --power-only mode to perf timechart that only
outputs the CPU power section of the SVG; this significantly
reduces the size of the SVG file, making even 30+ second traces
viewable with inkscape.
As a minor tweak for the same effect, the minimum text size is
decreased; current inkscape cannot zoom in deep enough to show text
this small, but it reduces inkscape compute time.

Subject: [PATCH 051/425] perf_event: Fix event group handling in
__perf_event_sched_*()
Paul Mackerras says:
"Actually, looking at this more closely, it has to be a group
leader anyway since it's at the top level of ctx->group_list. In
fact I see four places where we do:
list_for_each_entry(event, &ctx->group_list, group_entry) {
if (event == event->group_leader)
...
or the equivalent, three of which appear to have been introduced
by afedadf2 ("perf_counter: Optimize sched in/out of counters")
back in May by Peter Z.
As far as I can see the if () is superfluous in each case (a
singleton event will be a group of 1 and will have its
group_leader pointing to itself)."
[ See: http://marc.info/?l=linux-kernel&m=125361238901442&w=2 ]
And Peter Zijlstra points out this is a bugfix:
"The intent was to call event_sched_{in,out}() for single event
groups because that's cheaper than group_sched_{in,out}(),
however..
- as you noticed, I got the condition wrong, it should have read:
list_empty(&event->sibling_list)
- it failed to call group_can_go_on() which deals with ->exclusive.
- it also doesn't call hw_perf_group_sched_in() which might break
power."
[ See: http://marc.info/?l=linux-kernel&m=125369523318583&w=2 ]
Changelog v1->v2:
- Fix the title name according to Peter Zijlstra's suggestion
- Remove the comments and WARN_ON_ONCE() as Peter Zijlstra's
suggestion

Subject: [PATCH 054/425] x86: earlyprintk: Fix regression to handle
serial,ttySn as 1 arg
Commit c953094 ("early_printk: Allow more than one early console")
introduced a regression in the parsing of the earlyprintk= kernel
arguments.
If you specify "earlyprintk=serial,ttyS0,115200" as a kernel
argument, the "serial,ttyS" should be parsed as a single argument
and not as "serial" and then "ttyS".
Also update the documentation to reflect you can specify the ttyS
directly without the "serial" argument.

Subject: [PATCH 056/425] x86: Don't leak 64-bit kernel register values to
32-bit processes
While 32-bit processes can't directly access R8...R15, they can
gain access to these registers by temporarily switching themselves
into 64-bit mode.
Therefore, registers not preserved anyway by called C functions
(i.e. R8...R11) must be cleared prior to returning to user mode.

Subject: [PATCH 057/425] kmemtrace: Fix up tracer registration
Commit ddc1637af217dbd8bc51f30e6d24e84476a869a6 ("kmemtrace: Print
binary output only if 'bin' option is set") ended up inverting the
error detection logic. register_tracer() returns 0 on success,
which this change caused to treat as an error, resulting in:
[ 0.132000] Warning: could not register the kmem tracer
as well as bailing out of the initcall with an error value. This
restores the old logic.

Subject: [PATCH 059/425] drm/radeon/kms: Convert RS400/RS480 to new init path
& fix legacy VGA (V3)
Also cleanup register specific to RS400/RS480. This patch also fix
legacy VGA register used to disable VGA access we were programming
wrong register. Now we should properly disable VGA on r100 up to
rs400 asics. Note that RS400/RS480 resume is broken, it hangs the
computer while reprogramming dynamic clock, doesn't work either
without that patch. We need to spend more time investigating this
issue. Version 2 of the patch remove dead code that was left
commented out in the previous version. Version 3 correct the
placement on IGP of the VRAM inside GPU address space to match the
stollen RAM placement of IGP.

From d4550907157d8b3d5286157c15f1200c44842269 Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>

Subject: [PATCH 061/425] drm/radeon/kms: Convert R100 to new init path (V2)
New init path allow to simply asic initialization and make easier
to trace what happen on each different asic. We are removing most
callback. More cleanup should happen latter to remove even more
callback. Also cleanup register specific to R100,RV200,RV250.
Version 2 correct the placement on IGP of the VRAM inside GPU address
space to match the stollen RAM placement of IGP.

From 3bc6853593bd4fba357dc252b3cf60cd86a1d2ec Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Thu, 1 Oct 2009 09:39:24 +0200
Subject: [PATCH 062/425] drm/radeon/kms: Convert RS690/RS740 to new init path
(V2).
Also cleanup register specific to RS690/RS740. Version 2 add
missing header file for register, remove unecessary call to AGP
function and fix an indentation bug.

From c010f8000a925e08d84d9391e13dd297b9fdc393 Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Wed, 30 Sep 2009 22:09:06 +0200
Subject: [PATCH 063/425] drm/radeon/kms: Convert RS600 to new init path
New init path allow to simply asic initialization and make easier
to trace what happen on each different asic. We are removing most
callback. Do a massive RS600 register cleanup to clarify RS600
register, we are still bit fuzy on some register and waiting for
more informations. I don't have hw to test, so this patch is a
best effort to not break anythings and to try to improve things.

Subject: [PATCH 064/425] drm/radeon/kms: Remove old init path as no hw use it
anymore
This remove old init path and allow code cleanup, now all hw
use the new init path, see top of radeon.h for description of
this.

From 81cc35bfc19ebe4b823396fe4fef67a923360916 Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Thu, 1 Oct 2009 18:02:12 +0200
Subject: [PATCH 065/425] drm/radeon/kms: Fix R600 write back buffer
This split write back buffer handling into 3 functions,
wb_fini for cleanup, wb_enable/wb_disable for enabling/disabling
write back used for suspend/resume. This should fix
potential issue of letting the write back active before
suspending. We need to allocate memory in wb_enable because
we can only allocate once GART is running.

Subject: [PATCH 066/425] drm/radeon/kms: Fix R600/RV770 startup path & reset
We were calling reset unconditionaly in the startup path
this is bad we need to call GPU reset for a good reason
as after reset the GPU is in unknown states. To avoid any
more bad things to happen we now also unconditionaly
reinitialize the GPU after reset. This patch fix few issues
reported by different people regarding KMS & R6XX/RV7XX hw.

Subject: [PATCH 067/425] drm/radeon/kms: Fix R600/RV770 disable acceleration
path
When acceleration doesn't work we should free associated memory
and stop GPU block responsible for hardware acceleration so we
don't waste resource or let think one component of the driver that
a GPU feature is working/running while it doesn't actualy work.

Subject: [PATCH 070/425] ASoC: Fix SND_SOC_DAPM_LINE handling
Since the SND_SOC_DAPM_LINE can be input or output, additional check is
needed in order to determine if the widget is connected as input or
output.
When checking for connected outputs, if the widget is line, than check
if the sources list is not empty (line is connected as output)
For input endpoint check, when the widget is line, also check if the
sinks list is not empty (line is connected as input).

Subject: [PATCH 071/425] x86: EDAC: MCE: Fix MCE decoding callback logic
Make decoding of MCEs happen only on AMD hardware by registering a
non-default callback only on CPU families which support it.
While looking at the interaction of decode_mce() with the other MCE
code i also noticed a few other things and made the following
cleanups/fixes:
- Fixed the mce_decode() weak alias - a weak alias is really not
good here, it should be a proper callback. A weak alias will be
overriden if a piece of code is built into the kernel - not
good, obviously.
- The patch initializes the callback on AMD family 10h and 11h.
- Added the more correct fallback printk of:
No support for human readable MCE decoding on this CPU type.
Transcribe the message and run it through 'mcelog --ascii' to decode.
On CPUs that dont have a decoder.
- Made the surrounding code more readable.
Note that the callback allows us to have a default fallback -
without having to check the CPU versions during the printout
itself. When an EDAC module registers itself, it can install the
decode-print function.
(there's no unregister needed as this is core code.)
version -v2 by Borislav Petkov:
- add K8 to the set of supported CPUs
- always build in edac_mce_amd since we use an early_initcall now
- fix checkpatch warnings

This converts the MCE decoding logic into a standalone config
option which can be built-in or a module, the first one being the
default for MCEs happening early on in the boot process.
This, beyond being separated in a cleaner way, also saves RAM by
making the decoding logic modular.

Subject: [PATCH 076/425] [SCSI] scsi_dh_rdac: Fix for returning correct mode
select cmd return info
The function mode_select_handle_sense returns SCSI_DH_OK even when there is a sense code which is incorrect. Removing it so that it returns SCSI_DH_IO when there is sense that is not handled by this function.

Most code changes were made to support RR44xx adapters.
- add more PCI device ID.
- using PCI BAR[2] to access RR44xx IOP.
- using PCI BAR[0] to check and clear RR44xx IRQ.

Subject: [PATCH 078/425] [SCSI] bnx2i: Fix context mapping issue for
architectures with PAGE_SIZE != 4096
5706/5708/5709 devices allow driver/user to set page size. By default it is
set to 4096. Current drivers do not program this register based on
architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use
the defaults. So while mapping connection context memory (doorebll registers),
driver has to match page size used by the device. Included change fixes the
issue we uncovered during IA64 testing

Subject: [PATCH 079/425] [SCSI] sr: consider the last written sector when
determining media size
On certain cases, UDF disc doesn't report capacity correctly via
READ_CAPACITY but TOC or trackinfo contains valid information which
can be obtained using cdrom_get_last_written(). ide-cd considers both
values and uses the larger one. Do the same in sr. This fixes
bko#9668.

Subject: [PATCH 080/425] [SCSI] sg: Free data buffers after calling
blk_rq_unmap_user
Running sg_luns on s390x with CONFIG_DEBUG_PAGEALLOC enabled fails
with EFAULT from the SG_IO ioctl. The EFAULT is the result from
copy_to_user failing in this call chain:
sg_ioctl
sg_new_read
sg_finish_rem_req
blk_rq_unmap_user
__blk_rq_unmap_user
bio_uncopy_user
__bio_copy_iov
copy_to_user
The sg driver calls sg_remove_scat to free the memory pages before
calling blk_rq_unmap_user that tries to copy the data back to
userspace. Change the order to first call blk_rq_unmap_user before
freeing the pages in sg_remove_scat.

Subject: [PATCH 081/425] [SCSI] Retry ADD_TO_MLQUEUE return value for EH
commands
A target reset when I/O is ongoing might result
an eventual device offline, as scsi_eh_completed_normally()
might return ADD_TO_MLQUEUE in addition to the
advertised SUCCESS, FAILED, and NEEDS_RETRY.
Which is unfortunate as scsi_send_eh_cmnd() will
therefore map ADD_TO_MLQUEUE to FAILED instead of
the more appropriate NEEDS_RETRY.

Subject: [PATCH 082/425] [SCSI] Deprecate SCSI_PROT_*_CONVERT operations
The checksum format is orthogonal to whether the protection information
is being passed on beyond the HBA or not. It is perfectly valid to use
a non-T10 CRC with WRITE_STRIP and READ_INSERT.
Consequently it no longer makes sense to explicitly refer to the
conversion in the protection operation. Update sd_dif and lpfc
accordingly.

So far we have only issued DIF commands if CONFIG_BLK_DEV_INTEGRITY is

independent of protection information DMA. There are DIF-only host
adapters coming out that will be able to take advantage of this.
Move the relevant DIF bits to sd.c.

Subject: [PATCH 085/425] [SCSI] sd: Support disks formatted with DIF Type 2
Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands
when protection is enabled. Only the 32-byte variants are supported.
Implement support for issusing 32-byte READ/WRITE and enable Type 2
drives in the protection type detection logic.

Subject: [PATCH 092/425] [SCSI] mpt2sas: Added SCSIIO, Internal and high
priority memory pools to support multiple TM
1) create a pool of high priority message frames in the region of memory
between message frames and chains. The modifications are in
_base_allocate_memory_pools. Also create a seperate pool of memory for
internal commands located near the same region of memory. The pool of high
priority message frames is restriced by the facts->HighPriorityCredit.
2) Create additional API for accessing request message frames. New function
mpt2sas_base_get_smid_hpr is for highpriority request. New function
mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command
pointer. The mpt2sas_base_get_smid function is for requesting internal
commands.
3) Added new function _base_get_cb_idx to obtain the callback
index from one of the three pools of request message frames.
4) Removed wrapper functions _scsih_scsi_lookup_set and
_scsih_scsi_lookup_getclear. These were removed because this handling was
moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid.
5) The function mpt2sas_base_free_smid is modified so the request message
frames are put back on one of the three pools of request message frames.

From 77e63ed44305e89c0564f8292f9cd5764d4fddfb Mon Sep 17 00:00:00 2001
From: "Kashyap, Desai" <kashyap.desai@lsi.com>
Date: Mon, 14 Sep 2009 11:04:23 +0530
Subject: [PATCH 093/425] [SCSI] mpt2sas: Target Reset will be issued from
Interrupt context.
(1) Added three new functions to handle sending target resest and OP_REMOVE
from interrupt time, they are _scsih_tm_tr_send, _scsih_tm_tr_complete, and
_scsih_sas_control_complete. This code will create a link list of pending
target resets if there is no more available request in the hipriority
request queue. The list is stored in ioc->delayed_tr_list.
(2) All callback handler return type is changed from void to u8.
Now _base_interrupt will check for return type of callback handlers to
take decision of message frame is already freed or not.
In genral,
Return 1 meaning mf should be freed from _base_interrupt
0 means the mf is freed from function.

Subject: [PATCH 094/425] [SCSI] mpt2sas: Call init_completion on a per request
basis.
Now driver call init_completion on a per request basis. At some
point the wait_for_completion_timeout is not waiting for the timeout,
instead returning immediately, thus going into diag reset. This fix will
address all request using the wait_for_completion_timeout API. The previous
implimentation was only calling init_completion at driver
load time.

Subject: [PATCH 095/425] [SCSI] mpt2sas: Timeout occurred within the HANDSHAKE
logic while waiting on firmware to ACK.
Following a diag_reset, a request to send an ioc_init is timing out. The
timeout occurred within the HANDSHAKE logic while waiting on firmware to
acknowledge that the driver had wrote to the doorbell register. This was
root caused to a logic timeout in the firmware code. The proposed solution
is for the driver to call the udelay instead of msleep API in function where
its looping reading the interrupt status. In addition to this change, there
were two additional cases where we deleted the clearing interrupt status
outside handshake context.

Subject: [PATCH 099/425] [SCSI] zfcp: Fix initial device and cfdc for delayed
adapter allocation
With the change for delaying the allocation of zfcp_adapter, the
initial device parameter function has to first call
ccw_device_set_online which allocates the zfcp_adapter structure.
Change this and adapt the cfdc part accordingly.

Subject: [PATCH 100/425] [SCSI] zfcp: Fix oops during shutdown of offline
device
With the change that the zfcp_adapter struct is only allocated when
the device is set online, the shutdown handler has to check for a
non-existing zfcp_adapter struct. On the other hand, this check is not
necessary in the offline callback, since an online device has the
zfcp_adapter allocated and we go through the offline callback before
removing the ccw device.

cancel_work_sync is called while holding the config_mutex. But the
work that is being cancelled or flushed also uses the config_mutex.
Fix the resulting deadlock possibility by calling cancel_work_sync
earlier without holding the mutex. The best place to do is is after
offlining the device. No new port scan work will be scheduled for the
offline device, so this is a safe place to call cancel_work_sync.

The problem is that the chchp --vary 0 leads to zfcp first calling
fc_remote_port_delete which blocks all scsi devices on the remote
port. Calling scsi_remove_device later lets the sd driver issue a
SYNCHRONIZE_CACHE command. This command stays on the "stopped" request
requeue because the SCSI device is blocked. Fix this by first removing
the scsi and fc hosts which removes all scsi devices and do not use
scsi_remove_device.

Subject: [PATCH 105/425] x86: Simplify bound checks in the MTRR code
The current bound checks for copy_from_user in the MTRR driver are
not as obvious as they could be, and gcc agrees with that.
This patch simplifies the boundary checks to the point that gcc can
now prove to itself that the copy_from_user() is never going past
its bounds.

Subject: [PATCH 107/425] [SCSI] be2iscsi: Moving to pci_pools v3
This patch contains changes to use pci_pools for iscsi hdr
instead of pci_alloc_consistent. Here we alloc and free to pool
for every IO
v3:
- Remove cleanup loop in beiscsi_session_destroy
- Fixup for allocation failure handling in beiscsi_alloc_pdu
- Removed unused variable in beiscsi_session_destroy.

Subject: [PATCH 108/425] [SCSI] st: fix possible memory use after free after
MTSETBLK ioctl
A memory use after free bug can manifest if the MTSETBLK or SET_DENS_AND_BLK
ioctl features are used to set the tape's blocksize from 0 to non-zero.
After the driver sets the new block size, in this one case it calls
normalize_buffer() to free the device's internal data buffers. However, the
ioctl code assumes there is always a buffer and does not check or allocate
a buffer if there isn't one. So any following ioctl calls can corrupt
a part of memory by writing data to memory that the st driver had freed.
This patch removes the normalize_buffer() call and the specialness of
changing from a 0 to non-zero blocksize to fix the possible use of
memory after it has been freed by the st driver.

As of 559ee21d261a54c42594ef9405d27e9008eedf44 the actual refresh rate
is returned by the function of drm_mode_vrefresh, so multiply the refresh
rate by 1000 in TV mode validation.
At the same time the error is expanded from 10 to 1000.

Subject: [PATCH 110/425] [SCSI] qla2xxx: Fix NULL ptr deref bug in fail path
during queue create
Current code attempts to clean up resources when queue create fails and there it
invokes queue free call with a (NULL) pointer to the queue which could not be
allocated in the first place. Fix it by returning directly without invoking the
queue free call as no resources has been allocated at that point of time.

nested
When svm_vcpu_load is called while the vcpu is running in
guest mode the tsc adjustment made there is lost on the next
emulated #vmexit. This causes the tsc running backwards in
the guest. This patch fixes the issue by also adjusting the
tsc_offset in the emulated hsave area so that it will not
get lost.

inside the shadow page tables.
This is needed so we can balance the pagecount against mapcount
checking.
(Right now kvm increase the pagecount and does not increase the
mapcount when mapping page into shadow page table entry,
so when comparing pagecount against mapcount, you have no
reliable result.)

Subject: [PATCH 124/425] drm/radeon/kms: add support for "Surround View"
"Surround View" is an option in the system bios that
enables the AMD IGP chip in conjunction with a
discrete AMD card. However, since the IGP vbios is
part of the system bios it is not accessible via the
rom bar or the legacy vga location. When "Surround View"
is enabled in the system bios, the system bios puts a
copy of the IGP vbios image at the start of vram.
This patch adds support for reading the vbios image out
of vram on IGP cards.

Subject: [PATCH 127/425] drm/fb: add setcmap and fix 8-bit support.
This adds support for the setcmap api and fixes the 8bpp
support at least on radeon hardware. It adds a new load_lut
hook which can be called once the color map is setup.

Subject: [PATCH 132/425] e1000e: swap max hw supported frame size between
82574 and 82583
There appears to have been a mixup in the max supported jumbo frame size
between 82574 and 82583 which ended up disabling jumbo frames on the 82574
as a result. This patch swaps the two so that this issue is resolved.
This patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=14261

Subject: [PATCH 133/425] pktgen: Fix multiqueue handling
It is not currently possible to instruct pktgen to use one selected tx queue.
When Robert added multiqueue support in commit 45b270f8, he added
an interval (queue_map_min, queue_map_max), and his code doesnt take
into account the case of min = max, to select one tx queue exactly.
I suspect a high performance setup on a eight txqueue device wants
to use exactly eight cpus, and assign one tx queue to each sender.
This patchs makes pktgen select the right tx queue, not the first one.
Also updates Documentation to reflect Robert changes.

Subject: [PATCH 135/425] ALSA: hda - Fix invalid initializations for ALC861
auto mode
The recent auto-parser doesn't work for machines with a single output
with ALC861, such as Toshiba laptops, because alc_subsystem_id() sets
the hp_pins[0] while it's listed in line_outs[0].
This ends up with the doubled initialization of the same mixer widget,
and it mutes the DAC route because hp_pins has no DAC assigned.
To fix this problem, just check spec->autocfg.hp_outs and speaker_outs
so that they are really detected pins.

Subject: [PATCH 136/425] net: Support inclusion of <linux/socket.h> before
<sys/socket.h>
The following user-space program fails to compile:
#include <linux/socket.h>
#include <sys/socket.h>
int main() { return 0; }
The reason is that <linux/socket.h> tests __GLIBC__ to decide whether it
should define various structures and macros that are now defined for
user-space by <sys/socket.h>, but __GLIBC__ is not defined if no libc
headers have yet been included.
It seems safe to drop support for libc 5 now.

in profile_enable failure
When we call the profile_enable() callback of an event, we release the
shared perf event tracing buffers unconditionnaly in the failure path.
This is wrong because there may be other users of these. Then check the
total refcount before doing this.

In the event->profile_enable() failure path, we release the per cpu

Although free_percpu only wraps kfree for now, that may change in the
future so lets use the correct way.

held around their invocation. This is almost always true now
except when reading from sysfs:

Fixing this issue allows the call to effective_prio() in

Subject: [PATCH 146/425] Btrfs: fix deadlock on async thread startup
The btrfs async worker threads are used for a wide variety of things,
including processing bio end_io functions. This means that when
the endio threads aren't running, the rest of the FS isn't
able to do the final processing required to clear PageWriteback.
The endio threads also try to exit as they become idle and
start more as the work piles up. The problem is that starting more
threads means kthreadd may need to allocate ram, and that allocation
may wait until the global number of writeback pages on the system is
below a certain limit.
The result of that throttling is that end IO threads wait on
kthreadd, who is waiting on IO to end, which will never happen.
This commit fixes the deadlock by handing off thread startup to a
dedicated thread. It also fixes a bug where the on-demand thread
creation was creating far too many threads because it didn't take into
account threads being started by other procs.

Subject: [PATCH 147/425] OMAP3: PM: Prevent hang in prcm_interrupt_handler
There are two scenarios where a race condition could result in a hang
in the prcm_interrupt handler. These are:
1). Waiting for PRM_IRQSTATUS_MPU register to clear.
Bit 0 of the PRM_IRQSTATUS_MPU register indicates that a wake-up event
is pending for the MPU. This bit can only be cleared if the all the
wake-up events latched in the various PM_WKST_x registers have been
cleared. If a wake-up event occurred during the processing of the prcm
interrupt handler, after the corresponding PM_WKST_x register was
checked but before the PRM_IRQSTATUS_MPU was cleared, then the CPU
would be stuck forever waiting for bit 0 in PRM_IRQSTATUS_MPU to be
cleared.
2). Waiting for the PM_WKST_x register to clear.
Some power domains have more than one wake-up source. The PM_WKST_x
registers indicate the source of a wake-up event and need to be cleared
after a wake-up event occurs. When the PM_WKST_x registers are read and
before they are cleared, it is possible that another wake-up event
could occur causing another bit to be set in one of the PM_WKST_x
registers. If this did occur after reading a PM_WKST_x register then
the CPU would miss this event and get stuck forever in a loop waiting
for that PM_WKST_x register to clear.
This patch address the above race conditions that would result in a
hang.

Subject: [PATCH 148/425] OMAP3: PM: PRCM interrupt: check MPUGRPSEL register
PM_WKST register contents should be ANDed with the contents of the
MPUGRPSEL registers. Otherwise the MPU PRCM interrupt handler could
wind up clearing wakeup events meant for the IVA PRCM interrupt
handler. A future revision to this code should be to read a cached
version of MPUGRPSEL from the powerdomain code, since PRM reads are
relatively slow.

Subject: [PATCH 149/425] OMAP3: PM: PRCM interrupt: only handle selected PRCM
interrupts
Clearing wakeup sources is now only done when the PRM indicates a
wakeup source interrupt. Since we don't handle any other types of
PRCM interrupts right now, warn if we get any other type of PRCM
interrupt. Either code needs to be added to the PRCM interrupt
handler to react to these, or these other interrupts should be masked
off at init.
Updated after Jon Hunter's PRCM IRQ rework by Kevin Hilman.

Subject: [PATCH 150/425] OMAP3: PM: USBHOST: clear wakeup events on both hosts
USBHOST module has 2 fclocks (for HOST1 and HOST2), only one iclock
and only a single bit in the WKST register to indicate a wakeup event.
Because of the single WKST bit, we cannot know whether a wakeup event
was on HOST1 or HOST2, so enable both fclocks before clearing the
wakeup event to ensure both hosts can properly clear the event.

Subject: [PATCH 151/425] OMAP3: PM: Enable GPIO module-level wakeups
Currently, only GPIOs in the wakeup domain (GPIOs in bank 0) are
enabled as wakups. This patch also enables GPIOs in the PER
powerdomain (banks 2-6) to be used as possible wakeup sources.
In addition, this patch ensures that all GPIO wakeups can wakeup
the MPU using the PM_MPUGRPSEL_<pwrdm> registers.
NOTE: this doesn't enable the individual GPIOs as wakeups, this simply
enables the per-bank wakeups at the powerdomain level.
This problem was discovered by Mike Chan when preventing the CORE
powerdomain from going into retention/off. When CORE was allowed to
hit retention, GPIO wakeups via IO pad were working fine, but when
CORE remained on, GPIO module-level wakeups were not working properly.
To test, prevent CORE from going inactive/retention/off, thus
preventing the IO chain from being armed:
# echo 3 > /debug/pm_debug/core_pwrdm/suspend
This ensures that GPIO wakeups happen via module-level wakeups and
not via IO pad.
Tested on 3430SDP using the touchscreen GPIO (gpio 2, in WKUP)
Tested on Zoom2 using the QUART interrup GPIO (gpio 102, in PER)
Also, c.f. OMAP PM wiki for troubleshooting GPIO wakeup issues:

Subject: [PATCH 152/425] OMAP3: PM: introduce a new powerdomain walk helper
The 'pwrdm_for_each()' function walks powerdomains with a spinlock
locked, so the the callbacks cannot do anything which may sleep.
This patch introduces a 'pwrdm_for_each_nolock()' helper which does
the same, but without the spinlock locked. This fixes the following
lockdep warning:

Subject: [PATCH 155/425] rcu: Clean up code based on review feedback from Josh
Triplett, part 4
These issues identified during an old-fashioned face-to-face code
review extending over many hours. This group improves an existing
abstraction and introduces two new ones. It also fixes an RCU
stall-warning bug found while making the other changes.
o Make RCU_INIT_FLAVOR() declare its own variables, removing
the need to declare them at each call site.
o Create an rcu_for_each_leaf() macro that scans the leaf
nodes of the rcu_node tree.
o Create an rcu_for_each_node_breadth_first() macro that does
a breadth-first traversal of the rcu_node tree, AKA
stepping through the array in index-number order.
o If all CPUs corresponding to a given leaf rcu_node
structure go offline, then any tasks queued on that leaf
will be moved to the root rcu_node structure. Therefore,
the stall-warning code must dump out tasks queued on the
root rcu_node structure as well as those queued on the leaf
rcu_node structures.

Subject: [PATCH 156/425] rcu: Replace the rcu_barrier enum with pointer to
call_rcu*() function
The rcu_barrier enum causes several problems:
(1) you have to define the enum somewhere, and there is no
convenient place,
(2) the difference between TREE_RCU and TREE_PREEMPT_RCU causes
problems when you need to map from rcu_barrier enum to struct
rcu_state,
(3) the switch statement are large, and
(4) TINY_RCU really needs a different rcu_barrier() than do the
treercu implementations.
So replace it with a functionally equivalent but cleaner function
pointer abstraction.

In virtual environments (namely, Xen Dom0) virt <-> phys and

even outside such environments it is not really correct to do so).
When looking at memory below 1M, the latter translations should

Commit ffd71da4e3f ("panic: decrease oops_in_progress only after

As a result console_unblank() is not called, and on some systems
the user may not see the panic message.
Move it back up to before the unblanking.

Rich reported a lock imbalance in the futex code:
http://bugzilla.kernel.org/show_bug.cgi?id=14288
It's caused by the displacement of the retry_private label in
futex_wake_op(). The code unlocks the hash bucket locks in the
error handling path and retries without locking them again which
makes the next unlock fail.
Move retry_private so we lock the hash bucket locks when we retry.

Commit cd92204924fafbd5c7241dfd12ca3176d542e0c5 added
support for omap850. However, the patch accidentally
removed the wrong ifdef:
# define cpu_is_omap730() 1
# endif
#endif
+#else
+# if defined(CONFIG_ARCH_OMAP850)
+# undef cpu_is_omap850

+#endif
...
void omap2_check_revision(void);
#endif /* defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) */

-#endif
Instead of removing removing the #endif at the end of the file,
the #endif before #else should have been removed.
But we cannot have multiple #else statements as pointed out by
Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to:
- remove the non-multi-omap special handling, as we need to
detect between omap730 and omap850 anyways.
- add the missing #endif back to the end of the file

Subject: [PATCH 161/425] omap: Lock DPLL5 at boot
Lock DPLL5 at 120MHz at boot. The USBHOST 120MHz f-clock and
USBTLL f-clock are the only users of this DPLL, and 120MHz is
is the only recommended rate for these clocks.
With this patch, the 60 MHz ULPI clock is generated correctly.
Tested on an OMAP3430 SDP.

Subject: [PATCH 162/425] usb: r8a66597-udc unaligned fifo fix
Rework the r8a66597-udc fifo code to avoid unaligned accesses.
Without this patch unaligned exceptions will degrade the
USB performance. The exceptions come from the fact that
the usb fifo data buffers may be misaligned.
This patch updates the fifo access code to only use
insl()/outsl() and insw()/outsw() in the case of properly
aligned data buffers. The fallback case is that inl()/inw()
are used for misaligned buffer reads together with outb()
that is used for misaligned buffer writes.

Subject: [PATCH 163/425] drm/fb: add more correct 8/16/24/32 bpp fb support.
The previous patches had some unwanted side effects, I've fixed
the lack of 32bpp working, and fixed up 16bpp so it should also work.
this also adds the interface to allow the driver to set a preferred
console depth so for example low memory rn50 can set it to 8bpp.
It also catches 24bpp on cards that can't do it and forces 32bpp.
Tested on r100/r600/i945.

Subject: [PATCH 164/425] ahci: disable 64bit DMA by default on SB600s
Till now only one board, ASUS M2A-VM, can do 64bit dma with recent
BIOSen. Enabling 64bit DMA by default already broke three boards.
Enabling 64bit DMA isn't worth these regressions. Disable 64bit DMA
by default and enable it only on boards which are known to work.

Subject: [PATCH 166/425] ahci: display all AHCI 1.3 HBA capability flags (v2)
Update the AHCI driver to display all of the HBA capabilities defined in the
AHCI 1.3 specification. Some of these are in a new CAP2 (HBA Capabilities
Extended) register which is only defined on AHCI 1.2 or later. The spec says
that undefined registers should always return 0 on read, but to be safe we
assume a value of 0 unless the controller reports AHCI version 1.2 or later.
The value can also be retrieved through sysfs as with the existing capability
field.
For example, on an Intel Ibex Peak (PCH) controller:
ahci 0000:00:1f.2: flags: 64bit ncq sntf stag pm led clo pmp pio slum part ems
sxs apst
We don't do anything special with the new flags yet.
Also, change the code that displays the flags to use the same bit enumerations
that are used to control actual operation.

Subject: [PATCH 168/425] libata: implement more acpi filtering options
Currently libata-acpi can only filter DIPM among SATA feature enables
via _GTF. This patch adds the capability to filter out FPDMA non-zero
offset, in-order guarantee and auto-activation.

Subject: [PATCH 170/425] ahci: filter FPDMA non-zero offset enable for Aspire
3810T
Curiously, Aspire 3810T issues many SATA feature enable commands via
_GTF, of which one is invalid and another is not supported by the
drive. In the process, it also enables FPDMA non-zero offset.
However, the feature also needs to be supported and enabled from the
controller and it's wrong to enable it from _GTF unless the controller
can do it by default.
Currently, this ends up enabling FPDMA non-zero offset only on the
drive side leading to NCQ command failures and eventual disabling of
NCQ. This patch makes libata filter out FPDMA non-zero offset enable
for the machine.
This was reported by Marcus Meissner in bnc#522790.

Subject: [PATCH 176/425] Input: fix rx51 board keymap
The original driver was written with the KEY() macro defined as (col,
row) instead of (row, col) as defined by the matrix keypad
infrastructure. So the keymap was defined accordingly. Since the
driver that was merged upstream uses the matrix keypad infrastructure,
modify the keymap accordingly.
While we are at it, fix the comments in twl4030.h and define
PERSISTENT_KEY as (r,c) instead of (c, r)
Tested on a RX51 (N900) device.

Subject: [PATCH 183/425] [S390] module: fix memory leak in s390 module loader
The s390 version of module_frob_arch_sections allocates additional
syminfos for got and plt offsets. These syminfos are freed on
sucessful module load. If the module fails to load (e.g. missing
dependency when using insmod instead of modprobe) this area is not
freed.
This patch lets module_free free this area. Please note, we have to
set the pointer to NULL since module_free is called several times
from the generic code.

Subject: [PATCH 185/425] [S390] Fix memory leak in /proc/cio_ignore
There is a memory leak in /proc/cio_ignore. The iterator is allocated
in cio_ignore_proc_seq_start, but never freed in
cio_ignore_proc_seq_stop, because we cannot use the iterator
that was passed by seqfile. The seqfile interface passes the last
seen iterator to the stop function and not the first one. Since our
next function will return NULL at the end, the iter passed to
cio_ignore_proc_seq_stop is NULL. The original iter has leaked.
The solution is to use seq_open_private.
Found with kmemleak:
unreferenced object 0x1c720580 (size 32):
comm "head", pid 973, jiffies 4294958302

Subject: [PATCH 189/425] [S390] Fix enabled udelay for short delays.
When udelay() gets called with a delay that would expire before the
next clock event it reprograms the clock comparator.
When the interrupt happens the clock comparator won't be resetted
therefore the interrupt condition doesn't get cleared.
The result is an endless timer interrupt loop until the next clock
event would expire (stored in lowcore).
So udelay() usually would wait much longer for small delays than it
should.
Fix this by disabling the local tick which makes sure that the clock
comparator will be resetted when a timer interrupt happens.

Subject: [PATCH 192/425] [S390] ftrace: drop nmi protection
The function graph tracer used to have a protection against NMI
while entering a function entry tracing. But this is useless now,
the tracer is reentrant and the ring buffer supports NMI tracing.
Same as 07868b086cca784f4b532fc2ab574ec3a73b468a for x86.

Subject: [PATCH 199/425] [S390] Add EX_TABLE for addressing exception in
usercopy functions.
This patch adds an EX_TABLE entry to mvc{p|s|os} usercopy functions that
may be called with KERNEL_DS. In combination with collaborative memory
management, kernel pages marked as unused may trigger an adressing exception
in the usercopy functions. This fixes an unhandled addressing exception bug
where strncpy_from_user() is used with len > strnlen and KERNEL_DS, crossing
a page boundary to an unused page.

Subject: [PATCH 200/425] [S390] dasd: fix race condition in resume code
There is a race while re-reading the device characteristics. After
cleaning the memory area a cqr is build which reads the device
characteristics. This may take a rather long time and the device
characteristics structure is zero during this. Now it could be
possible that the block tasklet starts working and a new cqr will be
build. The build_cp command refers to the device characteristics
structure and this may lead into a divide by zero exception.
Fix this by re-reading the device characteristics into a temporary
structur and copy the data to the original structure. Also take the
ccwdev_lock.

Asm routines that end up having size equal to zero are not really
zero sized, and as now we do kernel_maps__fixup_sym_end, at least
for kernel routines this gets fixed.
A similar fixup needs to be done for the userspace bits as well,
but as this fixup started only because in /proc/kallsyms we don't
have the end address nor the function size, it appeared here first.

Subject: [PATCH 206/425] ALSA: hda - Don't pick up invalid HP pins in
alc_subsystem_id()
alc_subsystem_id() tries to pick up a headphone pin if not configured,
but this caused side-effects as the problem in commit
15870f05e90a365f8022da416e713be0c5024e2f.
This patch fixes the driver behavior to pick up invalid HP pins; at least,
the pins that are listed as the primary outputs aren't taken any more.

Subject: [PATCH 208/425] perf_event: Provide vmalloc() based mmap() backing
Some architectures such as Sparc, ARM and MIPS (basically
everything with flush_dcache_page()) need to deal with dcache
aliases by carefully placing pages in both kernel and user maps.
These architectures typically have to use vmalloc_user() for this.
However, on other architectures, vmalloc() is not needed and has
the downsides of being more restricted and slower than regular
allocations.

The state char variable S should be reassigned, if S == 0.
We are missing the state of the task that is going to sleep for the
context switch events (in the raw mode).
Fortunately the problem arises with the sched_switch/wake_up
tracers, not the sched trace events.
The formers are legacy now. But still, that was buggy.

Subject: [PATCH 210/425] sound: via82xx: move DXS volume controls to PCM
interface
The "VIA DXS" controls are actually volume controls that apply to the
four PCM substreams, so we better indicate this connection by moving the
controls to the PCM interface.
Commit b452e08e73c0e3dbb0be82130217be4b7084299e in 2.6.30 broke the
restoring of these volumes by "alsactl restore" that most distributions
use; the renaming in this patch cures that regression by preventing
alsactl from applying the old, wrong volume levels to the new controls.

Subject: [PATCH 211/425] Btrfs: fix possible softlockup in the allocator
Like the cluster allocating stuff, we can lockup the box with the normal
allocation path. This happens when we
1) Start to cache a block group that is severely fragmented, but has a decent
amount of free space.
2) Start to commit a transaction
3) Have the commit try and empty out some of the delalloc inodes with extents
that are relatively large.
The inodes will not be able to make the allocations because they will ask for
allocations larger than a contiguous area in the free space cache. So we will
wait for more progress to be made on the block group, but since we're in a
commit the caching kthread won't make any more progress and it already has
enough free space that wait_block_group_cache_progress will just return. So,
if we wait and fail to make the allocation the next time around, just loop and
go to the next block group. This keeps us from getting stuck in a softlockup.
Thanks,

Subject: [PATCH 212/425] futex: Nullify robust lists after cleanup
The robust list pointers of user space held futexes are kept intact
over an exec() call. When the exec'ed task exits exit_robust_list() is
called with the stale pointer. The risk of corruption is minimal, but
still it is incorrect to keep the pointers valid. Actually glibc
should uninstall the robust list before calling exec() but we have to
deal with it anyway.
Nullify the pointers after [compat_]exit_robust_list() has been
called.

fbdev: add mutex for fb_mmap locking
In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.
The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.
Solution: Don't use mutex before framebuffer registration.

Subject: [PATCH 222/425] NFS: Fix a default mount regression...
With the recent spate of changes, the nfs protocol version will now default
to 2 instead of 3, while the mount protocol version defaults to 3.
The following patch should ensure the defaults are consistent with the
previous defaults of vers=3,proto=tcp,mountvers=3,mountproto=tcp.
This fixes the bug

Subject: [PATCH 224/425] NFS: Fix port initialisation in nfs_remount()
The recent changeset 53a0b9c4c99ab0085a06421f71592722e5b3fd5f (NFS: Replace
nfs_parse_ip_address() with rpc_pton()) broke nfs_remount, since the call
to rpc_pton() will zero out the port number in data->nfs_server.address.
This is actually due to a bug in nfs_remount: it should be looking at the
port number in nfs_server.port instead...
This fixes bug

Subject: [PATCH 225/425] nfs: Avoid overrun when copying client IP address
string
As seen in <http://bugs.debian.org/549002>, nfs4_init_client() can
overrun the source string when copying the client IP address from
nfs_parsed_mount_data::client_address to nfs_client::cl_ipaddr. Since
these are both treated as null-terminated strings elsewhere, the copy
should be done with strlcpy() not memcpy().

Subject: [PATCH 226/425] NFSv4: Fix the referral mount code
Fix a typo which causes try_location() to use the wrong length argument
when calling nfs_parse_server_name(). This again, causes the initialisation
of the mount's sockaddr structure to fail.
Also ensure that if nfs4_pathname_string() returns an error, then we pass
that error back up the stack instead of ENOENT.

Subject: [PATCH 230/425] be2net: Bug Fix while accounting of multicast frames
during netdev stats update
While updating the statistics to be passed via the get_stats,
tx multicast frames were being accounted instead of rx multicast frames.
This patch fixes the bug. This patch is against the net-2.6 tree.

Subject: [PATCH 232/425] be2net: Bug fix to properly update ethtool
tx-checksumming after ethtool -K <ifname> tx off
This is a fix for a bug which was a result of wrong use of checksum offload flag.
The status of tx-checksumming was not changed from on to off
after a 'ethtool -K <ifname> tx off' operation.
Use the proper checksum offload flag NETIF_F_HW_CSUM instead of
NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM.
Patch is against net-2.6 tree.

Subject: [PATCH 233/425] libata: fix incorrect link online check during probe
While trying to work around spurious detection retries for
non-existent devices on slave links, commit
816ab89782ac139a8b65147cca990822bb7e8675 incorrectly added link
offline check logic before ata_eh_thaw() was called. This means that
if an occupied link goes down briefly at the time that offline check
was performed, device class will be cleared to ATA_DEV_NONE and libata
wouldn't retry thus failing detection of the device.
The offline check should be done after the port is thawed together
with online check so that such link glitches can be detected by the
interrupt handler and handled properly.

+changed via the MANUFACTURER_REQ command KCAPI_CMD_TRACE.

+length are logged. Otherwise, kernelcapi logs a readable representation of

Subject: [PATCH 241/425] isdn: avoid races in capidrv
In several places, capidrv sends a CAPI message to the ISDN
device and then updates its internal state accordingly.
If the response message from the device arrives before the
state is updated, it may be rejected or processed incorrectly.
Avoid these races by updating the state before emitting the
message.

Subject: [PATCH 251/425] rcu: Move rcu_barrier() to rcutree
Move the existing rcu_barrier() implementation to rcutree.c,
consistent with the fact that the rcu_barrier() implementation is
tied quite tightly to the RCU implementation.
This opens the way to simplify and fix rcutree.c's rcu_barrier()
implementation in a later patch.

Subject: [PATCH 252/425] rcu: Make hot-unplugged CPU relinquish its own RCU
callbacks
The current interaction between RCU and CPU hotplug requires that
RCU block in CPU notifiers waiting for callbacks to drain.
This can be greatly simplified by having each CPU relinquish its
own callbacks, and for both _rcu_barrier() and CPU_DEAD notifiers
to adopt all callbacks that were previously relinquished.
This change also eliminates the possibility of certain types of
hangs due to the previous practice of waiting for callbacks to be
invoked from within CPU notifiers. If you don't every wait, you
cannot hang.

Subject: [PATCH 253/425] rcu: Place root rcu_node structure in separate
lockdep class
Before this patch, all of the rcu_node structures were in the same lockdep
class, so that lockdep would complain when rcu_preempt_offline_tasks()
acquired the root rcu_node structure's lock while holding one of the leaf
rcu_nodes' locks.
This patch changes rcu_init_one() to use a separate
spin_lock_init() for the root rcu_node structure's lock than is
used for that of all of the rest of the rcu_node structures, which
puts the root rcu_node structure's lock in its own lockdep class.

Subject: [PATCH 254/425] Blackfin: convert to use arch_gettimeoffset()
Convert Blackfin to use GENERIC_TIME via the arch_getoffset()
infrastructure, reducing the amount of arch specific code we need to
maintain.
I've taken my best swing at converting this, but I'm not 100% confident
I got it right. My cross-compiler is now out of date (gcc4.2) so I
wasn't able to check if it compiled. Any assistance from arch
maintainers or testers to get this merged would be great.

Subject: [PATCH 255/425] Blackfin: mass clean up of copyright/licensing info
Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.
It also removes:
- verbose GPL text(refer to the top level ./COPYING file)
- file names (you are looking at the file)
- bug url (it's in the ./MAINTAINERS file)
- "or later" on GPL-2, when we did not have that right
It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

Subject: [PATCH 258/425] Blackfin: cplbinfo: drop d_path() hacks
The cplbinfo was using d_path() to figure out which cpu/cplb was being
parsed. As Al pointed out, this isn't exactly reliable as it assumes the
static VFS path to be unchanged, and it's just poor form. So use the
proc_create_data() to properly (and internally) pass the exact cpu/cplb
requested to the parser function.

Felix Radensky noted that chip resets were generating stack trace dumps.
This is because the driver is attempting to acquire the mdio bus mutex
while holding the tp->lock spinlock. The fix is to change the code such
that every phy access takes the tp->lock spinlock instead.

Subject: [PATCH 271/425] ethoc: use system memory as buffer
This patch enabled the ethoc to allocate system memory as buffer
when there is no dedicated buffer memory.
Some hardware designs may not have dedicated buffer memory such as
on chip or off chip SRAM. In this case, only one memory resource is
supplied in the platform data instead of two. Then a DMA buffer can
be allocated from system memory and used for the transfer.

Subject: [PATCH 273/425] NOHZ: update idle state also when NOHZ is inactive
Commit f2e21c9610991e95621a81407cdbab881226419b had unfortunate side
effects with cpufreq governors on some systems.
If the system did not switch into NOHZ mode ts->inidle is not set when
tick_nohz_stop_sched_tick() is called from the idle routine. Therefor
all subsequent calls from irq_exit() to tick_nohz_stop_sched_tick()
fail to call tick_nohz_start_idle(). This results in bogus idle
accounting information which is passed to cpufreq governors.
Set the inidle flag unconditionally of the NOHZ active state to keep
the idle time accounting correct in any case.

Subject: [PATCH 274/425] sis5513: fix PIO setup for ATAPI devices
Clear prefetch setting before potentially (re-)enabling it in
config_drive_art_rwp() so the transition of the device type on
the port from ATA to ATAPI (i.e. during warm-plug operation)
is handled correctly.
This is a really old bug (it probably goes back to very early
days of the driver) but it was only affecting warm-plug operation
until the recent "ide: try to use PIO Mode 0 during probe if
possible" change (commit 6029336426a2b43e4bc6f4a84be8789a047d139e).

(commit 6029336426a2b43e4bc6f4a84be8789a047d139e) so the revert was
incorrect (it simply replaced one regression with the other one).

Since patch_alc268() doesn't call set_capture_mixer() (due to its h/w

explicitly to set up the auto-mic routing. Otherwise the indices for
int/ext mics aren't set properly.

Simplify first loop and fixup printk formatting while at it.

Subject: [PATCH 282/425] amd64_edac: fix chip select handling
Different processor families support a different number of chip selects.
Handle this in a family-dependent way with the proper values assigned at
init time (see amd64_set_dct_base_and_mask).
Remove _DCSM_COUNT defines since they're used at one place and originate
from public documentation.

Subject: [PATCH 283/425] amd64_edac: fix DRAM base and limit extraction
On Fam10h and above, F1x[1, 0][7C:40] are DRAM Base/Limit registers
which specify the destination node of a DRAM address. Those address
boundaries are being extracted into ->dram_base[] and ->dram_limit[].
Correct the extraction masks to match the respective address bits.

Subject: [PATCH 284/425] amd64_edac: beef up DRAM error injection
When injecting DRAM ECC errors (F3xBC_x8), EccVector[15:0] is a bitmask
of which bits should be error injected when written to and holds the
payload of 16-bit DRAM word when read, respectively.
Add /sysfs members to show the DRAM ECC section/word/vector.
Fail wrong injection values entered over /sysfs instead of truncating
them.

If futex_wait_requeue_pi() wakes prior to requeue, we drop the
reference to the source futex_key twice, once in
handle_early_requeue_pi_wakeup() and once on our way out.
Remove the drop from the handle_early_requeue_pi_wakeup() and keep
the get/drops together in futex_wait_requeue_pi().

Subject: [PATCH 287/425] tracing: correct module boundaries for ftrace_release
When the module is about the unload we release its call records.
The ftrace_release function was given wrong values representing
the module core boundaries, thus not releasing its call records.
Plus making ftrace_release function module specific.

Due to legacy code from back when the dynamic tracer used a daemon,
only core kernel code was checking for failures. This is no longer
the case. We must check for failures any time we perform text modifications.

Subject: [PATCH 290/425] RDMA/iwcm: Don't call provider reject func with irqs
disabled
In commit cb58160e ("RDMA/iwcm: Reject the connection when the cm_id
is destroyed") a call to the provider's reject handler was added to
destroy_cm_id() to fix a provider endpoint leak. This call needs to
be done with interrupts enabled. So unlock and relock around this
call. This is safe because:
1) the provider will do nothing with this endpoint until the iwcm either
accepts or rejects.
2) the lock is only released after the iwcm state is changed, so an
errant iwcm app that is destroying -and- rejecting the connection
concurrently will get a failure on one of the calls.

Subject: [PATCH 295/425] drm/radeon/kms: Fallback to non AGP when acceleration
fails to initialize (v2)
When GPU acceleration is not working with AGP try to fallback to non
AGP GART (either PCI or PCIE GART). This should make KMS failure on
AGP less painfull. We still need to find out what is wrong when AGP
fails but at least user have a lot of more chances to get a working
configuration with acceleration. This patch also cleanup R600/RV770
fallback path so they use same code as others asics. Version 2
factorize agp disabling logic to avoid code duplication and bugs.

Subject: [PATCH 296/425] drm/radeon/kms: Fix AGP support for R600/RV770 family
(v2)
For AGP to work unmapped access must cover VRAM & AGP as
AGP is treated like VRAM by the GPU (ie physical address).
This patch properly setup the virtual memory system aperture
to cover AGP if AGP is enabled. It seems that there is memory
corruption after resume when using AGP (RV770 seems unaffected
thought). Version 2 just fix merge issue with updated AGP
fallback patch.

Subject: [PATCH 301/425] tracing: user local buffer variable for trace branch
tracer
Just using the tr->buffer for the API to trace_buffer_lock_reserve
is not good enough. This is because the tr->buffer may change, and we
do not want to commit with a different buffer that we reserved from.
This patch uses a local variable to hold the buffer that was used to
reserve and commit with.

Subject: [PATCH 306/425] Blackfin: fix framebuffer mmap bug for nommu
The patch added a special get_unmapped_area for framebuffer which
was hooked to the file ops in drivers/video/fbmem.c.
This is needed since v2.6.29-rc1 where nommu vma management was
updated, and mmap of framebuffer caused kernel BUG panic. You may turn
on "Debug the global anon/private NOMMU mapping region tree" config to
such message.
As Documentation/nommu-mmap.txt said,
"To provide shareable character device support, a driver must provide
a file->f_op->get_unmapped_area() operation. The mmap() routines will
call this to get a proposed address for the mapping."
With this change, user space should call mmap for framebuffer using
shared map. Or it can try shared map first, then private map if
failed. This shared map usage is now consistent between mmu and nommu.
The sys_ file may not be a good place for this patch. But there is a
similar one for sparc. I tested a similar patch on nios2nommu, though
I don't have a blackfin board to test.

Subject: [PATCH 308/425] Blackfin: convert to GENERIC_HARDIRQS_NO__DO_IRQ
Blackfin already sets proper flow handlers on all IRQs, and we don't rely
on __do_IRQ, therefore we can simply select GENERIC_HARDIRQS_NO__DO_IRQ.

Subject: [PATCH 309/425] ALSA: ICE1712/24 - Change the Multi Track Peak
control (level meters) from MIXER to PCM type
* PLEASE NOTE - this change requires the corresponding update of
envy24control for ice1712 - kind of an ABI change.
* The "Multi Track Peak" control is read-only level meters indicator.
* The control is VERY confusing to most users since it is currently displayed
in regular mixers. E.g. alsamixer ignores its read-only status
and allows changing the levels with keys which makes no sense.

Subject: [PATCH 311/425] ALSA: ice1724: increase SPDIF and independent stereo
buffer sizes
Increase the default and maximum PCM buffer prellocation size for ice1724's
SPDIF and independent stereo pair outputs to 256K, which is the hardware's
maximum supported size. This allows a reduction in interrupt rate and
potentially power usage when an application is not latency-critical.

Subject: [PATCH 312/425] ksm: more on default values
Adjust the max_kernel_pages default to a quarter of totalram_pages,
instead of nr_free_buffer_pages() / 4: the KSM pages themselves come from
highmem, and even on a 16GB PAE machine, 4GB of KSM pages would only be
pinning 32MB of lowmem with their rmap_items, so no need for the more
obscure calculation (nor for its own special init function).
There is no way for the user to switch KSM on if CONFIG_SYSFS is not
enabled, so in that case default run to KSM_RUN_MERGE.
Update KSM Documentation and Kconfig to reflect the new defaults.

Subject: [PATCH 317/425] cgroups: update documentation of cgroups tasks and
procs files
Update documentation of cgroups tasks and procs files
Document the cgroup.procs file.
Clarify the semantics of the cgroup.procs and tasks files. Although the
current cgroup.procs interface returns a sorted and uniqified list of
pids, potential future performance enhancements could result in those
properties being removed - explicitly document this aspect of the API.
There are no existing users of cgroup.procs, so compatibility isn't an
issue. There are users of the "tasks" file, but none that would appear to
break in the event of the sorted property being broken. The standard
"libcpuset" explicitly sorts the results of reading from the tasks file,
and "libcg" and other users don't appear to care about ordering.

Subject: [PATCH 328/425] mm, perf_event: Make vmalloc_user() align base kernel
virtual address to SHMLBA
When a vmalloc'd area is mmap'd into userspace, some kind of
co-ordination is necessary for this to work on platforms with cpu
D-caches which can have aliases.
Otherwise kernel side writes won't be seen properly in userspace
and vice versa.
If the kernel side mapping and the user side one have the same
alignment, modulo SHMLBA, this can work as long as VM_SHARED is
shared of VMA and for all current users this is true. VM_SHARED
will force SHMLBA alignment of the user side mmap on platforms with
D-cache aliasing matters.
The bulk of this patch is just making it so that a specific
alignment can be passed down into __get_vm_area_node(). All
existing callers pass in '1' which preserves existing behavior.
vmalloc_user() gives SHMLBA for the alignment.
As a side effect this should get the video media drivers and other
vmalloc_user() users into more working shape on such systems.

Subject: [PATCH 329/425] x86, timers: Check for pending timers after (device)
interrupts
Now that range timers and deferred timers are common, I found a
problem with these using the "perf timechart" tool. Frans Pop also
reported high scheduler latencies via LatencyTop, when using
iwlagn.
It turns out that on x86, these two 'opportunistic' timers only get
checked when another "real" timer happens. These opportunistic
timers have the objective to save power by hitchhiking on other
wakeups, as to avoid CPU wakeups by themselves as much as possible.
The change in this patch runs this check not only at timer
interrupts, but at all (device) interrupts. The effect is that:
1) the deferred timers/range timers get delayed less
2) the range timers cause less wakeups by themselves because
the percentage of hitchhiking on existing wakeup events goes up.
I've verified the working of the patch using "perf timechart", the
original exposed bug is gone with this patch. Frans also reported
success - the latencies are now down in the expected ~10 msec
range.

Subject: [PATCH 330/425] NFSv4: Kill nfs4_renewd_prepare_shutdown()
The NFSv4 renew daemon is shared between all active super blocks that refer
to a particular NFS server, so it is wrong to be shutting it down in
nfs4_kill_super every time a super block is destroyed.
This patch therefore kills nfs4_renewd_prepare_shutdown altogether, and
leaves it up to nfs4_shutdown_client() to also shut down the renew daemon
by means of the existing call to nfs4_kill_renewd().

Subject: [PATCH 334/425] xfs: implement ->dirty_inode to fix timestamp
handling
This is picking up on Felix's repost of Dave's patch to implement a
.dirty_inode method. We really need this notification because
the VFS keeps writing directly into the inode structure instead
of going through methods to update this state. In addition to
the long-known atime issue we now also have a caller in VM code
that updates c/mtime that way for shared writeable mmaps. And
I found another one that no one has noticed in practice in the FIFO
code.
So implement ->dirty_inode to set i_update_core whenever the
inode gets externally dirtied, and switch the c/mtime handling to
the same scheme we already use for atime (always picking up
the value from the Linux inode).
Note that this patch also removes the xfs_synchronize_atime call
in xfs_reclaim it was superflous as we already synchronize the time
when writing the inode via the log (xfs_inode_item_format) or the
normal buffers (xfs_iflush_int).
In addition also remove the I_CLEAR check before copying the Linux
timestamps - now that we always have the Linux inode available
we can always use the timestamps in it.
Also switch to just using file_update_time for regular reads/writes -
that will get us all optimization done to it for free and make
sure we notice early when it breaks.

Subject: [PATCH 335/425] xfs: fix xfs_quiesce_data
We need to do a synchronous xfs_sync_fsdata to make sure the superblock
actually is on disk when we return.
Also remove SYNC_BDFLUSH flag to xfs_sync_inodes because that particular
flag is never checked.
Move xfs_filestream_flush call later to only release inodes after they
have been written out.

Sort out ->sync_fs to not perform a superblock writeback for the wait = 0 case
as that is just an optional first pass and the superblock will be written back
properly in the next call with wait = 1. Instead perform an opportunistic
quota writeback to have less work later. Also remove the freeze special case
as we do a proper wait = 1 call in the freeze code anyway.
Also rename the function to xfs_fs_sync_fs to match the normal naming
convention, update comments and avoid calling into the laptop_mode logic on
an error.

Subject: [PATCH 339/425] fix readahead calculations in
xfs_dir2_leaf_getdents()
This is for bug #850,
http://oss.sgi.com/bugzilla/show_bug.cgi?id=850
XFS file system segfaults , repeatedly and 100% reproducable in 2.6.30 , 2.6.31
The above only showed up on a CONFIG_XFS_DEBUG=y kernel, because
xfs_bmapi() ASSERTs that it has been asked for at least one map,
and it was getting 0.
The root cause is that our guesstimated "bufsize" from xfs_file_readdir
was fairly small, and the
bufsize -= length;
in the loop was going negative - except bufsize is a size_t, so it
was wrapping to a very large number.
Then when we did
ra_want = howmany(bufsize + mp->m_dirblksize,
mp->m_sb.sb_blocksize) - 1;
with that very large number, the (int) ra_want was coming out
negative, and a subsequent compare:
if (1 + ra_want > map_blocks ...
was coming out -true- (negative int compare w/ uint) and we went
back to xfs_bmapi() for more, even though we did not need more,
and asked for 0 maps, and hit the ASSERT.
We have kind of a type mess here, but just keeping bufsize from
going negative is probably sufficient to avoid the problem.

Subject: [PATCH 342/425] Btrfs: delay clearing EXTENT_DELALLOC for compressed
extents
When compression is on, the cow_file_range code is farmed off to
worker threads. This allows us to do significant CPU work in parallel
on SMP machines.
But it is a delicate balance around when we clear flags and how. In
the past we cleared the delalloc flag immediately, which was safe
because the pages stayed locked.
But this is causing problems with the newest ENOSPC code, and with the
recent extent state cleanups we can now clear the delalloc bit at the
same time the uncompressed code does.

Subject: [PATCH 343/425] Btrfs: release delalloc reservations on extent item
insertion
This patch fixes an issue with the delalloc metadata space reservation
code. The problem is we used to free the reservation as soon as we
allocated the delalloc region. The problem with this is if we are not
inserting an inline extent, we don't actually insert the extent item until
after the ordered extent is written out. This patch does 3 things,
1) It moves the reservation clearing stuff into the ordered code, so when
we remove the ordered extent we remove the reservation.
2) It adds a EXTENT_DO_ACCOUNTING flag that gets passed when we clear
delalloc bits in the cases where we want to clear the metadata reservation
when we clear the delalloc extent, in the case that we do an inline extent
or we invalidate the page.
3) It adds another waitqueue to the space info so that when we start a fs
wide delalloc flush, anybody else who also hits that area will simply wait
for the flush to finish and then try to make their allocation.
This has been tested thoroughly to make sure we did not regress on
performance.

Subject: [PATCH 344/425] Btrfs: async delalloc flushing under space pressure
This patch moves the delalloc flushing that occurs when we are under space
pressure off to a async thread pool. This helps since we only free up
metadata space when we actually insert the extent item, which means it takes
quite a while for space to be free'ed up if we wait on all ordered extents.
However, if space is freed up due to inline extents being inserted, we can
wake people who are waiting up early, and they can finish their work.

Subject: [PATCH 345/425] Btrfs: optimize fsync for the single writer case
This patch optimizes the tree logging stuff so it doesn't always wait 1 jiffie
for new people to join the logging transaction if there is only ever 1 writer.
This helps a little bit with latency where we have something like RPM where it
will fdatasync every file it writes, and so waiting the 1 jiffie for every
fdatasync really starts to add up.

We should favour PMB mappings when the physical address cannot be
reached with 29-bits.

Subject: [PATCH 351/425] sh: Don't allocate smaller sized mappings on every
iteration
Currently, we've got the less than ideal situation where if we need to
allocate a 256MB mapping we'll allocate four entries like so,
entry 1: 128MB
entry 2: 64MB
entry 3: 16MB
entry 4: 16MB
This is because as we execute the loop in pmb_remap() we will
progressively try mapping the remaining address space with smaller and
smaller sizes. This isn't good because the size we use on one iteration
may be the perfect size to use on the next iteration, for instance when
the initial size is divisible by one of the PMB mapping sizes.
With this patch, we now only need two entries in the PMB to map 256MB of
address space,
entry 1: 128MB
entry 2: 128MB

subvolumne
The use of btrfs_dentry_delete is removing dentries from the
dcache when deleting subvolumne. btrfs_dentry_delete ignores
negative dentries. This is incorrect since if we don't remove
the negative dentry, its parent dentry can't be removed.

Subject: [PATCH 358/425] Btrfs: fix file clone ioctl for bookend extents
The file clone ioctl was incorrectly taking the offset into the
extent on disk into account when calculating the length of the
cloned extent.
The length never changes based on the offset into the physical extent.
Test case:
fallocate -l 1g image
mke2fs image
bcp image image2
e2fsck -f image2
(errors on image2)
The math bug ends up wrapping the length of the extent, and things
go wrong from there.

Subject: [PATCH 360/425] hwmon: (asus_atk0110) Refactor the code
Refactor the code of the new style interface around GGRP (enumeration) and
GITM (read) helpers to mimic ASL code. Also switch the read path to use
dynamic buffers (handled by ACPI core) since ASUS expanded the return buffer
(ASBF) in newer boards (e.g. P7P55D).

Subject: [PATCH 361/425] hwmon: (asus_atk0110) Enable the EC
On newer ASUS boards (e.g. P7P55D) the EC (that - among other things - is
responsible for updating the readings from the hwmon sensors) is disabled
by default since ASUS detected conflict with some tools under Windows.
The following patch checks the state of the EC and enable it if needed;
under Linux, native drivers are locked out from ACPI owned resources so
there's no risk of conflict.

Subject: [PATCH 366/425] IRQ: Change __softirq_pending to unsigned int in
asm-generic/hardirq.h.
Since the beginnings in aafe4dbed0bf6cbdb2e9f03e1d42f8a540d8541d
("asm-generic: add generic versions of common headers") the generic
version of <asm/hardirq.h> defined __softirq_pending as unsigned long.
Which is different from other architectures for no apparent good reason
and was causing the following warning:
kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick':
kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'
Reported and initial patch by Wu Zhangjin <wuzhangjin@gmail.com>.
Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
Acked-by: Arnd Bergmann <arnd@arndb.de>
[ Arnd points out that we really should make sure parisc and alpha are
ok with this, since they have also been converted to use the generic
hardirq.h file. But neither seems to use it, although parisc does
build a IRQSTAT_SIRQ_PEND #define into asm-offsets - but that also
appears unused.. - Linus ]

Subject: [PATCH 369/425] Staging: remove cowloop driver
The author has found a number of problems with the current version
of this driver in the current kernel, and is reworking it to get
things working again. Because of that, it would be better to remove
the driver now and add it back in a future kernel release.

- tristate "copy-on-write pseudo Block Driver"
- depends on BLOCK
- default n
- ---help---
- Cowloop is a "copy-on-write" pseudo block driver. It can be
- stacked on top of a "real" block driver, and catches all write
- operations on their way from the file systems layer above to
- the real driver below, effectively shielding the lower driver
- from those write accesses. The requests are then diverted to
- an ordinary file, located somewhere else (configurable). Later
- read requests are checked to see whether they can be serviced
- by the "real" block driver below, or must be pulled in from
- the diverted location. More information and userspace tools to
- use the driver are on the project's website

-/*
-** COWLOOP block device driver (2.6 kernel compliant)
-** =======================================================================
-** Read-write loop-driver with copy-on-write functionality.
-**
-** Synopsis:
-**
-** modprobe cowloop [maxcows=..] [rdofile=..... cowfile=.... [option=r]]
-**
-** Definition of number of configured cowdevices:
-** maxcows= number of configured cowdevices (default: 16)
-** (do not confuse this with MAXCOWS: absolute maximum as compiled)
-**
-** One pair of filenames can be supplied during insmod/modprobe to open
-** the first cowdevice:
-** rdofile= read-only file (or filesystem)
-** cowfile= storage-space for modified blocks of read-only file(system)
-** option=r repair cowfile automatically if it appears to be dirty
-**
-** Other cowdevices can be activated via the command "cowdev"
-** whenever the cowloop-driver is loaded.
-**
-** The read-only file may be of type 'regular' or 'block-device'.
-**
-** The cowfile must be of type 'regular'.
-** If an existing regular file is used as cowfile, its contents will be
-** used again for the current read-only file. When the cowfile has not been
-** closed properly during a previous session (i.e. rmmod cowloop), the
-** cowloop-driver refuses to open it unless the parameter "option=r" is
-** specified.
-**
-** Layout of cowfile:
-**
-** +-----------------------------+
-** | cow head block | MAPUNIT bytes
-** |-----------------------------|
-** | | MAPUNIT bytes
-** |--- ---|
-** | | MAPUNIT bytes
-** |--- ---|
-** | used-block bitmap | MAPUNIT bytes
-** |-----------------------------|
-** | gap to align start-offset |
-** | to 4K multiple |
-** |-----------------------------| <---- start-offset cow blocks
-** | |
-** | written cow blocks | MAPUNIT bytes
-** | ..... |
-**
-** cowhead block:
-** - contains general info about the rdofile which is related
-** to this cowfile
-**
-** used-block bitmap:
-** - contains one bit per block with a size of MAPUNIT bytes
-** - bit-value '1' = block has been written on cow
-** '0' = block unused on cow
-** - total bitmap rounded to multiples of MAPUNIT
-**

-** Major modifications:
-**
-** 200405 Ported to kernel-version 2.6 Hendrik-Jan Thomassen
-** 200405 Added cowhead to cowfile to garantee
-** consistency with read-only file Gerlof Langeveld
-** 200405 Postponed flushing of bitmaps to improve
-** performance. Gerlof Langeveld
-** 200405 Inline recovery for dirty cowfiles. Gerlof Langeveld
-** 200502 Redesign to support more cowdevices. Gerlof Langeveld
-** 200502 Support devices/file > 2 Gbytes. Gerlof Langeveld
-** 200507 Check for free space to expand cowfile. Gerlof Langeveld
-** 200902 Upgrade for kernel 2.6.28 Hendrik-Jan Thomassen
-**
-** Inspired by
-** loop.c by Theodore Ts'o and
-** cloop.c by Paul `Rusty' Russell & Klaus Knopper.
-**
-** Design-considerations:
-**
-** For the first experiments with the cowloop-driver, the request-queue
-** made use of the do_generic_file_read() which worked fine except
-** in combination with the cloop-driver; that combination
-** resulted in a non-interruptible hangup of the system during
-** heavy load. Other experiments using the `make_request' interface also
-** resulted in unpredictable system hangups (with proper use of spinlocks).
-**
-** To overcome these problems, the cowloop-driver starts a kernel-thread
-** for every active cowdevice.
-** All read- and write-request on the read-only file and copy-on-write file
-** are handled in the context of that thread.
-** A scheme has been designed to wakeup the kernel-thread as
-** soon as I/O-requests are available in the request-queue; this thread
-** handles the requests one-by-one by calling the proper read- or
-** write-function related to the open read-only file or copy-on-write file.
-** When all pending requests have been handled, the kernel-thread goes
-** back to sleep-state.
-** This approach requires some additional context-switches; however the
-** performance loss during heavy I/O is less than 3%.

From: Pekka Enberg <penberg@cs.helsinki.fi>
Date: Mon, 21 Sep 2009 12:52:15 +0300
Subject: [PATCH 370/425] Staging: w35und: Fix ->beacon_int breakage
Commit f424afa17899408cbd267a4c4534ca6fc9d8f71c ("mac80211: remove
deprecated API") removed ->beacon_int from struct ieee80211_conf. Fix
breakage in w35und by setting beacon period in ->add_interface to
bss_conf.beacon_int.

Subject: [PATCH 371/425] Staging: winbond: implement prepare_multicast and fix
API usage
This patch adds a prepare_multicast callback for the winbond driver
to properly receive mc_count in ->configure_filter.
This also fixes incompatible pointer assignment build errors because
->configure_filter had changed.
This is build tested only, but that's more than the original code received.

Subject: [PATCH 374/425] Staging: p9auth: a few fixes
1. The memory into which we copy 'u1@u2' needs space for u1, @,
u2, and a final \0 which strcat copies in.
2. Strsep changes the value of its first argument. So use a
temporary variable to pass to it, so we pass the original
value to kfree!
3. Allocate an extra char to user_buf, because we need a trailing \0
since we later kstrdup it.
I am about to send out an LTP testcase for this driver, but
in addition the correctness of the hashing can be verified as
follows:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
char in[41], out[20];
unsigned int v;
int i, ret;
ret = read(STDIN_FILENO, in, 40);
if (ret != 40)
exit(1);
in[40] = '\0';
for (i = 0; i < 20; i++) {
sscanf(&in[2*i], "%02x", &v);
out[i] = v;
}
write(STDOUT_FILENO, out, 20);
}
as root, to test userid 501 switching to uid 0, choosing
'random' string 'ab':
echo -n "501@0" > plain
openssl sha1 -hmac 'ab' plain |awk '{ print $2 '} > dgst
./unhex < dgst > dgst.u
mknod /dev/caphash 504 0
mknod /dev/capuse 504 1
chmod ugo+w /dev/capuse
cat dgst.u > /dev/caphash

echo "501@0@ab" > /dev/capuse

Subject: [PATCH 389/425] USB: ftdi_sio: clean up read completion handler
Remove superfluous error checks in completion handler:
- No need to check private data and urb pointers as we check urb-status
before dereferencing priv (which is not freed until urb has been killed
on close).
- No need to check tty as it is checked again when processing.
- No need to check urb->number_of_packets on bulk urb.
Note that both private data and tty are checked again before processing
(possibly from work queue which also is cancelled on close).

Subject: [PATCH 390/425] USB: ftdi_sio: re-implement read processing
- Re-structure read processing.
- Kill obsolete work queue and always push to tty in completion handler.
- Use tty_insert_flip_string instead of per character push when
possible.
- Fix stalled-read regression in 2.6.31 by using urb status to
determine when port is closed rather than port count.
- Fix race with open/close by checking ASYNCB_INITIALIZED in
unthrottle.
- Kill private rx_flag and lock and use throttle flags in
usb_serial_port instead.

Subject: [PATCH 393/425] USB: serial: don't call release without attach
This patch (as1295) fixes a recently-added bug in the USB serial core.
If certain kinds of errors occur during probing, the core may call a
serial driver's release method without previously calling the attach
method. This causes some drivers (io_ti in particular) to perform an
invalid memory access.
The patch adds a new flag to keep track of whether or not attach has
been called.

Subject: [PATCH 400/425] USB: xhci: Handle canceled URBs when HC dies.
When the host controller dies (e.g. it is removed from a PCI card slot),
the xHCI driver cannot expect commands to complete. The buggy code this
patch fixes would mark an URB as canceled and then expect the URB to be
completed when the stop endpoint command completed. That would never
happen if the host controller was dead, so the USB core would just hang in
the disconnect code.
If the host controller died, and the driver asks to cancel an URB, free
any structures associated with that URB and immediately give it back.

When the host controller dies or is removed while a device is plugged in,
the USB core will attempt to deallocate the struct usb_device. That will
call into xhci_free_dev(). This function used to attempt to submit a
disable slot command to the host controller and clean up the device
structures when that command returned. Change xhci_free_dev() to skip the
command submission and just free the memory if the host controller died.

Subject: [PATCH 412/425] USB: storage: When a device returns no sense data,
call it a Hardware Error
This patch (as1294) fixes a problem that has plagued users for several
kernel releases. Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors. The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit. In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.
The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error. This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.
This fixes a large part of Bugzilla #14118.

Subject: [PATCH 413/425] USB: ehci: Fix isoc scheduling boundary checking.
The EHCI driver does some bounds checking when it's scheduling an iTD for
an active endpoint. It sets the local variable start to
stream->next_uframe and moves that variable further in the schedule if
necessary. However, the driver fails to do anything with start before
jumping to the ready label and setting the URB's starting frame to
stream->next_uframe. Alan Stern confirms the EHCI driver should set
stream->next_uframe to start before jumping.

Subject: [PATCH 416/425] USB: serial: fix assumption that throttle/unthrottle
cannot sleep
many serial subdrivers are clearly written as if throttle/unthrottle
cannot sleep. This leads to unneeded atomic submissions. This
patch converts affected drivers in a way to makes very clear that
throttle/unthrottle can sleep. Thus future misdesigns can be avoided
and efficiency and reliability improved.
This removes any such assumption using GFP_KERNEL and spin_lock_irq()

Subject: [PATCH 419/425] headers: remove sched.h from interrupt.h
After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

Subject: [PATCH 420/425] ROMFS: fix length used with romfs_dev_strnlen()
function
An interestingly corrupted romfs file system exposed a problem with the
romfs_dev_strnlen function: it's passing the wrong value to its helpers.
Rather than limit the string to the length passed in by the callers, it
uses the size of the device as the limit.

Subject: [PATCH 421/425] pci: increase alignment to make more space for hidden
code
As reported in
http://bugzilla.kernel.org/show_bug.cgi?id=13940
on some system when acpi are enabled, acpi clears some BAR for some
devices without reason, and kernel will need to allocate devices for
them. It then apparently hits some undocumented resource conflict,
resulting in non-working devices.
Try to increase alignment to get more safe range for unassigned devices.

SMSC911X_IRQ_POLARITY_ACTIVE_LOW, is normally stored in the irq_polarity
field, so I have renamed the field in the first initialization to that.

Subject: [PATCH 425/425] [ARM] pxa: workaround errata #37 by not using half
turbo switching
PXA27x Errata #37 implies system will hang when switching into or out of
half turbo (HT bit in CLKCFG) mode, workaround this by not using it.
