Commit bd119c6923
"Disintegrate asm/system.h for Tile"
created the asm/switch_to.h file, but did not add an include
of it to all its users.
Also, commit b4816afa39
"Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h"
introduced the concept of asm/cmpxchg.h but the tile arch
never got one. Fork the cmpxchg content out of the asm/atomic.h
file to create one.

Merge tag 'for-linus' of git://github.com/rustyrussell/linux
Pull cpumask cleanups from Rusty Russell:
"(Somehow forgot to send this out; it's been sitting in linux-next, and
if you don't want it, it can sit there another cycle)"
I'm a sucker for things that actually delete lines of code.
Fix up trivial conflict in arch/arm/kernel/kprobes.c, where Rusty fixed
a user of &cpu_online_map to be cpu_online_mask, but that code got
deleted by commit b21d55e98a ("ARM: 7332/1: extract out code patch
function from kprobes").

b74f05d61b x86: kvmclock: abstract save/restore sched_clock_state
restore_sched_clock_state() methods use percpu data, therefore
they must run after %gs is initialized, but before mtrr_bp_restore()
(due to lockstat using sched_clock).
Move it to the correct place.

Pull perf updates and fixes from Ingo Molnar:
"It's mostly fixes, but there's also two late items:
- preliminary GTK GUI support for perf report
- PMU raw event format descriptors in sysfs, to be parsed by tooling
The raw event format in sysfs is a new ABI. For example for the 'CPU'
PMU we have:
aldebaran:~> ll /sys/bus/event_source/devices/cpu/format/*
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/any
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/cmask
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/edge
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/event
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/inv
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/offcore_rsp
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/pc
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/umask
those lists of fields contain a specific format:
aldebaran:~> cat /sys/bus/event_source/devices/cpu/format/offcore_rsp
config1:0-63
So, those who wish to specify raw events can now use the following
event format:
-e cpu/cmask=1,event=2,umask=3
Most people will not want to specify any events (let alone raw
events), they'll just use whatever default event the tools use.
But for more obscure PMU events that have no cross-architecture
generic events the above syntax is more usable and a bit more
structured than specifying hex numbers."

This does a sweeping change fixing up all the missing system_misc.h and

ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.
I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

On gccs that support AVX it's a good idea to disable that too, similar to
how SSE2, SSE1 etc. are already disabled. This prevents the compiler
from generating AVX ever implicitely.

Commit 68b7f715 ("nommu: ptrace support") added definitions for
PT_TEXT_ADDR and friends, as well as adding ptrace support for reading
from these magic offsets.
Unfortunately, this has probably never worked, since ptrace_read_user
predicates reading on off < sizeof(struct user), returning -EIO
otherwise.
This patch moves the offset size check until after we have tried to
match it against either a magic value or an offset into pt_regs.

Some improper formatting caused the .eh_frame generation to fail,
resulting in gcc/g++ testsuite failures with regards to unwinding through

Presently there's no SHmedia support plugged in for the dwarf unwinder.
While it's trivial to provide an SHmedia version of dwarf_read_arch_reg(),
the general sh64 case is more complicated in that the TLB miss handler
uses a locked down set of registers for optimization (including the frame
pointer) which we need for the unwind table generation.
While freeing up the frame pointer for use in the TLB miss handler is
reasonably straightforward, it's still more trouble than it's worth, so
we simply restrict the unwinder to 32-bit for now.

When processor is being hot-added to the system, acpi_map_lsapic invokes
ACPI _MAT method to find APIC ID and flags, verifies that returned structure
is indeed ACPI's local APIC structure, and that flags contain MADT_ENABLED
bit. Then saves APIC ID, frees structure - and accesses structure when
computing arguments for acpi_register_lapic call. Which sometime leads
to acpi_register_lapic call being made with second argument zero, failing
to bring processor online with error 'Unable to map lapic to logical cpu
number'.
As lapic->lapic_flags & ACPI_MADT_ENABLED was already confirmed to be non-zero
few lines above, we can just pass unconditional ACPI_MADT_ENABLED to the
acpi_register_lapic.

The X86_32-only disable_hlt/enable_hlt mechanism was used by the
32-bit floppy driver. Its effect was to replace the use of the
HLT instruction inside default_idle() with cpu_relax() - essentially
it turned off the use of HLT.
This workaround was commented in the code as:
"disable hlt during certain critical i/o operations"
"This halt magic was a workaround for ancient floppy DMA
wreckage. It should be safe to remove."
H. Peter Anvin additionally adds:
"To the best of my knowledge, no-hlt only existed because of
flaky power distributions on 386/486 systems which were sold to
run DOS. Since DOS did no power management of any kind,
including HLT, the power draw was fairly uniform; when exposed
to the much hhigher noise levels you got when Linux used HLT
caused some of these systems to fail.
They were by far in the minority even back then."
Alan Cox further says:
"Also for the Cyrix 5510 which tended to go castors up if a HLT
occurred during a DMA cycle and on a few other boxes HLT during
DMA tended to go astray.
Do we care ? I doubt it. The 5510 was pretty obscure, the 5520
fixed it, the 5530 is probably the oldest still in any kind of
use."
So, let's finally drop this.

There has long been a limitation using software breakpoints with a
kernel compiled with CONFIG_DEBUG_RODATA going back to 2.6.26. For
this particular patch, it will apply cleanly and has been tested all
the way back to 2.6.36.
The kprobes code uses the text_poke() function which accommodates
writing a breakpoint into a read-only page. The x86 kgdb code can
solve the problem similarly by overriding the default breakpoint
set/remove routines and using text_poke() directly.
The x86 kgdb code will first attempt to use the traditional
probe_kernel_write(), and next try using a the text_poke() function.
The break point install method is tracked such that the correct break
point removal routine will get called later on.

The default irq_disable() sematics are to mark the interrupt disabled,
but keep it unmasked. If the interrupt is delivered while marked
disabled, the low level interrupt handler masks it and marks it
pending. This is important for detecting wakeup interrupts during
suspend and for edge type interrupts to avoid losing interrupts.
fixup_irqs() moves the interrupts away from an offlined cpu. For
certain interrupt types it needs to mask the interrupt line before
changing the affinity. After affinity has changed the interrupt line
is unmasked again, but only if it is not marked disabled.
This breaks the lazy irq disable semantics and causes problems in
suspend as the interrupt can be lost or wakeup functionality is
broken.
Check irqd_irq_masked() instead of irqd_irq_disabled() because
irqd_irq_masked() is only set, when the core code actually masked the
interrupt line. If it's not set, we unmask the interrupt and let the
lazy irq disable logic deal with an eventually incoming interrupt.

This adopts a trimmed down version of the MIPS port mangling interface
limited to the I/O swabbing for platforms that can't use little endian
accessors. For platforms with mixed I/O spaces involving PCI it will
still be necessary to enable byte swapping at the host controller level.
Attention needs to be paid to all of host controller endianness, CPU
endianness, and whether I/O accesses are explicitly swapped or not via
SWAP_IO_SPACE. Fortunately the platforms that need this are in the
minority.

crashkernel reservation need know the total memory size. Current
get_total_mem simply use max_pfn - min_low_pfn. It is wrong because it
will including memory holes in the middle.
Especially for kvm guest with memory > 0xe0000000, there's below in qemu
code: qemu split memory as below:
if (ram_size >= 0xe0000000 ) {
above_4g_mem_size = ram_size - 0xe0000000;
below_4g_mem_size = 0xe0000000;
} else {
below_4g_mem_size = ram_size;
}
So for 4G mem guest, seabios will insert a 512M usable region beyond of
4G. Thus in above case max_pfn - min_low_pfn will be more than original
memsize.
Fixing this issue by using memblock_phys_mem_size() to get the total
memsize.

We have lots of infrastructure in place to partition multi-core systems
such that we have a group of CPUs that are dedicated to specific task:
cgroups, scheduler and interrupt affinity, and cpuisol= boot parameter.
Still, kernel code will at times interrupt all CPUs in the system via IPIs
for various needs. These IPIs are useful and cannot be avoided
altogether, but in certain cases it is possible to interrupt only specific
CPUs that have useful work to do and not the entire system.
This patch set, inspired by discussions with Peter Zijlstra and Frederic
Weisbecker when testing the nohz task patch set, is a first stab at trying
to explore doing this by locating the places where such global IPI calls
are being made and turning the global IPI into an IPI for a specific group
of CPUs. The purpose of the patch set is to get feedback if this is the
right way to go for dealing with this issue and indeed, if the issue is
even worth dealing with at all. Based on the feedback from this patch set
I plan to offer further patches that address similar issue in other code
paths.
This patch creates an on_each_cpu_mask() and on_each_cpu_cond()
infrastructure API (the former derived from existing arch specific
versions in Tile and Arm) and uses them to turn several global IPI
invocation to per CPU group invocations.
Core kernel:
on_each_cpu_mask() calls a function on processors specified by cpumask,
which may or may not include the local processor.
You must not call this function with disabled interrupts or from a
hardware interrupt handler or from a bottom half handler.
arch/arm:
Note that the generic version is a little different then the Arm one:
1. It has the mask as first parameter
2. It calls the function on the calling CPU with interrupts disabled,
but this should be OK since the function is called on the other CPUs
with interrupts disabled anyway.
arch/tile:
The API is the same as the tile private one, but the generic version
also calls the function on the with interrupts disabled in UP case
This is OK since the function is called on the other CPUs
with interrupts disabled.

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.
Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures. In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h

Pull a few more things for powerpc by Benjamin Herrenschmidt:
- Anton's did some recent improvements to EPOW event reporting on
pSeries (power supply failures and such). The patches are self
contained enough and replace really nasty code so I felt it should
still go in
- I did the vio driver registration change Greg requested, I don't see
the point of leaving that til the next merge window
- The remaining EEH changes I said were still pending to get rid of the
EEH references from the generic struct device_node
- A few more iSeries removal bits

Add information about LVT offset assignments to better debug firmware
bugs related to this. See following examples.
# dmesg | grep -i 'offset\|ibs'
LVT offset 0 assigned for vector 0xf9
[Firmware Bug]: cpu 0, try to use APIC500 (LVT offset 0) for vector 0x10400, but the register is already in use for vector 0xf9 on another cpu
[Firmware Bug]: cpu 0, IBS interrupt offset 0 not available (MSRC001103A=0x0000000000000100)
Failed to setup IBS, -22
In this case the BIOS assigns both offsets for MCE (0xf9) and IBS
(0x400) vectors to offset 0, which is why the second APIC setup (IBS)
failed.

Now that userspace is making use of kernel-provided sanitized headers for
working out supported interfaces, we need to be a bit more diligent with
matching the syscall definitions with their actual wiring/support state.
In theory it shouldn't hurt anything since sys_ni_syscall will ultimately
do the right thing, but there's also not much need to lie about legacy
x86 syscalls that we've never supported.
This tightens things up a bit for uClibc at least.

"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."

970 and Power4 don't support "continuous sampling" which means that
when we aren't in marked instruction sampling mode (marked events),
SIAR isn't updated with the last instruction sampled before the
perf interrupt. On those processors, we must thus use the exception
SRR0 value as the sampled instruction pointer.
Those processors also don't support the SIPR and SIHV bits in MMCRA
which means we need some kind of heuristic to decide if SIAR values
represent kernel or user addresses.

which tells us nothing about what happened. Even worse, if we

Add code to printk some useful information when we get EPOW events.
We want to make it clear that we have an error, that it was
reported by firmware and that the RTAS error log will have more
detailed information. eg:
Ambient temperature too high reported by firmware.
Check RTAS error log for details
Depending on the error encountered, we now issue an immediate or

Currently, the existing PHBs are retrieved from the FDT (Flat
Device Tree) based on the name of FDT node. Specificly, those
FDT nodes whose names have prefix "pci" are regarded as PHBs.
That's inappropriate because some PCI bridges possibilly have
names leading with "pci". It caused EEH is enabled on same
PCI devices for towice.
The patch fixes the above issue. Besides, the PHBs are expected
to be figured out from FDT before enable EEH on them. Therefore,
it's resonable to retrieve the PHBs from the global linked list
traced by variable "hose_list" insteading poking them from FDT.
For the EEH implementation on pSeries platform, RTAS is critical
because all low-level functions are implemented based on RTAS.
Therefore, we should make sure "/rtas" OF node is available and
ready before to enable EEH core. However, it actually introduced
duplicate since the previous pSeries platform dependent initialization
function already do the check. Besides, we want to make eeh core
platform independent, so RTAS related staff should be removed there.
The patch removes the duplicate check on "/rtas" OF node for eeh
core.

These are all specific to some driver. They are typically the platform
side of a change in the drivers directory, such as adding a new driver
or extending the interface to the platform. In cases where there is no
maintainer for the driver, or the maintainer prefers to have the
platform changes in the same branch as the driver changes, the patches
to the drivers are included as well.
A much smaller set of driver updates that depend on other branches
getting merged first will be sent later.
The new export of tegra_chip_uid conflicts with other changes in fuse.c.

This new subsystem provides a common way to talk to secondary processors
on an SoC, e.g. a DSP, GPU or service processor, using virtio as the
transport. In the long run, it should replace a few dozen vendor
specific ways to do the same thing, which all never made it into the
upstream kernel. There is a broad agreement that rpmsg is the way to
go here and several vendors have started working on replacing their
own subsystems.
Two branches each add one virtio protocol number. Fortunately the
numbers were agreed upon in advance, so there are only context changes.

These changes are all specific to one board only. We're trying to keep
the number of board files low, but generally board level updates are
ok on platforms that are working on moving towards DT based probing,
which will eventually lead to removing them.

ams_delta_config and the addition of a lot of other data. The Kconfig
file has two changes in the same line, and in exynos, the power domain

We should not ever enable IRQs until we're fully set up. This opens up
a window where interrupts can hit the cpu and interrupts can do
wakeups, wakeups need state that isn't set-up yet, in particular this
cpu isn't elegible to run tasks, so if any cpu-affine task that got
created in CPU_UP_PREPARE manages to get a wakeup, its affinity mask
will get broken and we'll run into lots of 'interesting' problems.

This patch is part of a set which fixes unnecessary flash erase and write errors
resulting from the MTD CFI driver turning off vpp while an erase is in progress.
This patch allows physmap_set_vpp() calls to be nested by adding a reference
counter.
omap1_set_vpp() already used a reference counter. Since it is called from
physmap_set_vpp(), omap1_set_vpp() can now be simplified.
simtec_nor_vpp() already disabled hard interrupts. Since it is called from

Both functions are mostly identical.
The differences are:
- x86_32's cpu_idle() makes use of check_pgt_cache(), which is a
nop on both x86_32 and x86_64.
- x86_64's cpu_idle() uses enter/__exit_idle/(), on x86_32 these
function are a nop.
- In contrast to x86_32, x86_64 calls rcu_idle_enter/exit() in
the innermost loop because idle notifications need RCU.
Calling these function on x86_32 also in the innermost loop
does not hurt.
So we can merge both functions.

x86_64 UML is unable to load modules if more than 504MiB
of memory are used.
This happens because on x86_64 the UML process has a quite high
start address (typically around 0x6000000).
If UML's memory is larger than 504MiB VMALLOC_START happens to be after
0x8000000. This is no problem unless one loads a module which was built
with R_X86_64_32S relocations.
Symbols with a location > 0x8000000 cannot be used with R_X86_64_32S
To deal with this x86_64 UML has to be compiled with -mcmodel=large
such that no R_X86_64_32S relocations are used.

"[RFC - PATCH 0/7] consolidation of BUG support code."
https://lkml.org/lkml/2012/1/26/525
--
The changes shown here are to unify linux's BUG support under
the one <linux/bug.h> file. Due to historical reasons, we have
some BUG code in bug.h and some in kernel.h -- i.e. the support for
BUILD_BUG in linux/kernel.h predates the addition of linux/bug.h,
but old code in kernel.h wasn't moved to bug.h at that time. As
a band-aid, kernel.h was including <asm/bug.h> to pseudo link them.
This has caused confusion[1] and general yuck/WTF[2] reactions.
Here is an example that violates the principle of least surprise:
CC lib/string.o
lib/string.c: In function 'strlcat':
lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON'
make[2]: *** [lib/string.o] Error 1
$
$ grep linux/bug.h lib/string.c
#include <linux/bug.h>
$
We've included <linux/bug.h> for the BUG infrastructure and yet we
still get a compile fail! [We've not kernel.h for BUILD_BUG_ON.]
Ugh - very confusing for someone who is new to kernel development.
With the above in mind, the goals of this changeset are:
1) find and fix any include/*.h files that were relying on the
implicit presence of BUG code.
2) find and fix any C files that were consuming kernel.h and
hence relying on implicitly getting some/all BUG code.
3) Move the BUG related code living in kernel.h to <linux/bug.h>
4) remove the asm/bug.h from kernel.h to finally break the chain.
During development, the order was more like 3-4, build-test, 1-2.
But to ensure that git history for bisect doesn't get needless
build failures introduced, the commits have been reorderd to fix
the problem areas in advance.

Supports both little and big endian. Unaligned loads are emitted

Hardware integer division is used if it is available.

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check for shared signals we're about to block.
Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures. In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

Before replacing an instruction, the ftrace code determines what the old
instruction should be and verifies that that's what's really there in
memory before replacing it. This is useful if for example a bug in
mcountrecord causes it to record wrong locations.
However, in cases where we replace call sites in entry-common.S, these
checks are not needed. For these, we currently just memcpy() the memory
content and then "verify" it -- this is quite useless and can be
removed.

The kexec machine crash code can be called in interrupt context via a
sysrq trigger made using the magic key combination. If the irq chip
dealing with the serial interrupt is using the fasteoi flow handler,
then we will never EOI the interrupt because the interrupt handler will
be fatal. In the case of a GIC, this results in the crash kernel not
receiving interrupts on that CPU interface.
This patch adds code (based on the PowerPC implementation) to EOI any
pending interrupts on the crash CPU before masking and disabling all
interrupts. Secondary cores are not a problem since they are placed into
a cpu_relax() loop via an IPI.

"This one covers stuff which Arnd is waiting for me to push, as this is
shared between both our trees and probably other trees elsewhere.
Essentially, this contains:
- AMBA primecell device initializer updates - mostly shrinking the
size of the device declarations in platform code to something more
reasonable.
- Getting rid of the NO_IRQ crap from AMBA primecell stuff.
- Nicolas' idle cleanups. This in combination with the restart
cleanups from the last merge window results in a great many
mach/system.h files being deleted."

This series for the OpenRISC architecture consists of mostly trivial fixups.
The most interesting bits of the series are:
* A fix to the timer code whereby the shortest trigger period is set to
100 cycles; previously, it was possible to set this to 1 cycle, but by
the time the register was written, that time had already passed and the
timer interrupt would not go off until the cycle counter had gone a full
cycle.
* Allowing a device tree binary to be passed in to the kernel from u-boot.
The OpenRISC architecture has been recently merged into upstream u-boot,
so this change gets OpenRISC Linux into sync with that project.

Since we no longer need the VM_ALWAYSDUMP flag, let's use the freed bit
for 'VM_NODUMP' flag. The idea is is to add a new madvise() flag:
MADV_DONTDUMP, which can be set by applications to specifically request
memory regions which should not dump core.
The specific application I have in mind is qemu: we can add a flag there
that wouldn't dump all of guest memory when qemu dumps core. This flag
might also be useful for security sensitive apps that want to absolutely
make sure that parts of memory are not dumped. To clear the flag use:
MADV_DODUMP.

The motivation for this patchset was that I was looking at a way for a
qemu-kvm process, to exclude the guest memory from its core dump, which
can be quite large. There are already a number of filter flags in
/proc/<pid>/coredump_filter, however, these allow one to specify 'types'
of kernel memory, not specific address ranges (which is needed in this
case).
Since there are no more vma flags available, the first patch eliminates
the need for the 'VM_ALWAYSDUMP' flag. The flag is used internally by
the kernel to mark vdso and vsyscall pages. However, it is simple
enough to check if a vma covers a vdso or vsyscall page without the need
for this flag.
The second patch then replaces the 'VM_ALWAYSDUMP' flag with a new
'VM_NODUMP' flag, which can be set by userspace using new madvise flags:
'MADV_DONTDUMP', and unset via 'MADV_DODUMP'. The core dump filters
continue to work the same as before unless 'MADV_DONTDUMP' is set on the
region.
The qemu code which implements this features is at:
http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch
In my testing the qemu core dump shrunk from 383MB -> 13MB with this
patch.
I also believe that the 'MADV_DONTDUMP' flag might be useful for
security sensitive apps, which might want to select which areas are
dumped.
This patch:
The VM_ALWAYSDUMP flag is currently used by the coredump code to
indicate that a vma is part of a vsyscall or vdso section. However, we
can determine if a vma is in one these sections by checking it against
the gate_vma and checking for a non-NULL return value from
arch_vma_name(). Thus, freeing a valuable vma bit.

As described in e6fa16ab9c ("signal: sigprocmask() should do

incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.
Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures. In the past some architectures got this code
wrong, so using this helper function should stop that from happening
again.

As suggested by Suresh Siddha and Yinghai Lu:
For x2apic pre-enabled systems, apic driver is set already early
through early_acpi_boot_init()/early_acpi_process_madt()/
acpi_parse_madt()/default_acpi_madt_oem_check() path so that
apic_id_valid() checking will be sufficient during MADT and SRAT
parsing.
For non-x2apic pre-enabled systems, all apic ids should be less
than 255.
This allows us to substitute the checks in
arch/x86/kernel/acpi/boot.c::acpi_parse_x2apic() and
arch/x86/mm/srat.c::acpi_numa_x2apic_affinity_init() with
apic->apic_id_valid().
In addition we can avoid feigning the x2apic cpu feature in the
NumaChip apic code.
The following apic drivers have separate apic_id_valid()
functions which will accept x2apic type IDs :
x2apic_phys
x2apic_cluster
x2apic_uv_x
apic_numachip

Add a perf PMU to access the CPU-measurement counter facility CPUM CF.
CPUM CF provides multiple counter sets for measuring generic,
problem-state, and crypto activaties. Also an extended counter set for
the IBM System z10 and IBM z196 mainframes is available.
Counters from the basic and problem-state counter set are mapped to
generic perf hardware events. Other counters are accessible through
raw events.
For a list of available counter sets and counters, see:
- The Load-Program-Parameter and the CPU-Measurement Facilities (SA23-2260)
- The CPU-Measurement Facility Extended Counters Definition for
z10 and z196 (SA23-2261)

Prepare the measurement facility which is currently only used by oprofile
for multiple users. To achieve that the measurement alert interrupt control
bit needs to be protected. The measurement alert definitions are moved
to a header file and an interrupt mask is added so that users can discard
interrupts if they are for a different measurement subsystem.

- on x86: RDPMC weirdness due to being 40/48 bits and not sign-extending

This patch fix the problem with rootfs on JFFS2 with early printk
console turned on.
The origin version used TLB63 for temporary early printk mapping.
The code expect that kernel is not able to use all 64 TLB entries
till early printk console is remapped by ioremap. After that
temporary mapping on TLB63 is silently lost.
This expectation give the opportunity to have early console pretty
early.
Microblaze systems with JFFS2 rootfs with early printk console turned on
used more than 64 TLB entries before kernel can remap early console.
Based on that kernel does access to bad area because early printk mapping
is rewritten.
This patch introduces tlb_skip variable which dynamically stores number
of skipped TLB entries from the TLB0. skip_tlb=2 means that TLB0 and TLB1
should be skipped.
MICROBLAZE_TLB_SKIP defines how many TLB is skipped at the kernel start.
They can be used for user purpose.
TLB 63 is used for temporary LMB mapping (MICROBLAZE_LMB_TLB_ID).
Also clean TLBLO when kernel starts.
For specific kernel sizes kernel can use just one TLB. Detect this case
and use the second TLB for general purpose.
Change _tlbia function to flush TLB entries from tlb_skip to TLB_SIZE.
Export tlb_skip size through debugfs.

Systems with small amount of memory need to be handled
differently. Linux can't allocate the whole 32MB with two TLBs
because then there is no MMU protection.
Signed-off-by: Michal Simek <monstr@monstr.eu>
The main reason is bug because of dynamic TLB allocation.
U-BOOT didn't disable dcache and then writing to physical address
from ASM wan't visible for reading through MMU.
Disabling caches and clearing all flags from previous code
is good to do so.

Fix how many pages are allocated in mapin_ram. It is lowmem_size
not setup CONFIG_LOWMEM_SIZE because it is the same for all systems.
Which means that wrong pages are allocated if memory size is smaller
than CONFIG_LOWMEM_SIZE. It has dramatic impact on bootup time.

power management data to the hypervisor. It also inhibits cpufreq
scaling drivers to load so that only the hypervisor can make power
management decisions - fixing a weird perf bug.
- Function Level Reset (FLR) support in the Xen PCI backend.
Fixes:

- Compile warnings and constify fixes
- Change over to use percpu_xxx instead of this_cpu_xxx

On platforms such as OMAP3, certain variants may not have IVA, SGX
or some specific component. We currently have a check to aid fixing
wrong population of OPP entries for issues such as typos. This however
causes a conflict with valid requirement where the SoC variant does
not actually have the module present.
So, reduce the severity of the print to a debug statement and skip
registering that specific OPP, but continue down the list.

On OMAP4, recently a synchronisation bug is discovered by hardware
team, which leads to incorrect timer value read from 32K sync timer
IP when the IP is comming out of idle.
The issue is due to the synchronization methodology used in the SYNCTIMER IP.
The value of the counter register in 32kHz domain is synchronized to the OCP
domain register only at count up event, and if the OCP clock is switched off,
the OCP register gets out of synch until the first count up event after the
clock is switched back -at the next falling edge of the 32kHz clock.
Further investigation revealed that it applies to gptimer1 and watchdog timer2
as well which may run on 32KHz. This patch fixes the issue for all the
applicable modules.
The BUG has not made it yet to the OMAP errata list and it is applicable to
OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps.
By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU
is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces
the OCP clock to be running and allow the counter value to be updated properly
in the OCP clock domain.
The bug is going to fixed in future OMAP versions.

The problem occurs on !CONFIG_VM86 kernels [1] when a kernel-mode task
returns from a system call with a pending signal.
A real-life scenario is a child of 'khelper' returning from a failed
kernel_execve() in ____call_usermodehelper() [ kernel/kmod.c ].
kernel_execve() fails due to a pending SIGKILL, which is the result of
"kill -9 -1" (at least, busybox's init does it upon reboot).
The loop is as follows:
* syscall_exit_work:
- work_pending: // start_of_the_loop
- work_notify_sig:
- do_notify_resume()
- do_signal()
- if (!user_mode(regs)) return;
- resume_userspace // TIF_SIGPENDING is still set
- work_pending // so we call work_pending => goto
// start_of_the_loop

Pull drm main changes from Dave Airlie:
"This is the main drm pull request, I'm probably going to send two more
smaller ones, will explain below.
This contains a patch that is also in the fbdev tree, but it should be
the same patch, it added an API for hot unplugging framebuffer
devices, and I need that API for a new driver.
It also contains some changes to the i2c tree which Jean has acked,
and one change to moorestown platform stuff in x86.
Highlights:
- new drivers: UDL driver for USB displaylink devices, kms only,
should support correct hotplug operations.
- core: i2c speedups + better hotplug support, EDID overriding via
firmware interface - allows user to load a firmware for a broken
monitor/kvm from userspace, it even has documentation for it.
- exynos: new HDMI audio + hdmi 1.4 + virtual output driver
- gma500: code cleanup
- radeon: cleanups, CS optimisations, streamout support and pageflip
fix
- nouveau: NVD9 displayport support + more reclocking work
- i915: re-enabling GMBUS, finish gpu patch (might help hibernation
who knows), missed irq fixes, stencil tiling fixes, interlaced
support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
semaphore fixes
As well as the usual bunch of cleanups and fixes all over the place.
I've got two things I'd like to merge a bit later:
a) AMD support for all their new radeonhd 7000 series GPU and APUs.
AMD dropped this a bit late due to insane internal review
processes, (please AMD just follow Intel and let open source guys
ship stuff early) however I don't want to penalise people who own
this hardware (since its been on sale for 3-4 months and GPU hw
doesn't exactly have a lifetime in years) and consign them to
using closed drivers for longer than necessary. The changes are
well contained and just plug into the driver new gpu functionality
so they should be fairly regression proof. I just want to give
them a bit of a run on the hw AMD kindly sent me.
b) drm prime/dma-buf interface code. This is just infrastructure
code to expose the dma-buf stuff to drm drivers and to userspace.
I'm not planning on pushing any driver support in this cycle
(except maybe exynos), but I'd like to get the infrastructure code
in so for the next cycle I can start getting the driver support
into the individual drivers. We have started driver support for
i915, nouveau and udl along with I think exynos and omap in
staging. However this code relies on the dma-buf tree being
pulled into your tree first since it needs the latest interfaces
from that tree. I'll push to get that tree sent asap.
(oh and any warnings you see in i915 are gcc's fault from what anyone
can see)."
Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new
msic_thermal_platform_data() thermal function being added next to the

Here is the first big update chunk of sound stuff for 3.4-rc1.
In the common sound infrastructure, there are a few changes for
dynamic PCM support (used in ASoC) and a few clean-ups. Majority of
changes are found, as usual, in HD-audio and ASoC.
Some highlights of HD-audio changes:
- All the long-standing static quirk codes for Realtek codec were
finally removed by fixing and extending the Realtek auto-parser.
- The mute-LED control is standardized over all HD-audio codec
drivers using the extended vmaster hook.
- The vmaster slave mixer elements are initialized to 0dB as default
so that the user won't be annoyed by the silent output after
updates, e.g. due to the additions of new elements.
- Other many fix-ups for the misc HD-audio devices.
In the ASoC side, this is a very active release, including a quite a
few framework enhancements. Some highlights:
- Support for widgets not associated with a CODEC, an important part
of the dynamic PCM framework.
- A library factoring out the common code shared by dmaengine based
DMA drivers contributed by Lars-Peter Clausen. This will save a lot
of code and make it much easier to deploy enhancements to
dmaengine.
- Support for binary controls, used for providing runtime
configuration of algorithm coefficients.
- A new DAPM widget type for regulator supplies allowing drivers for
devices that can power down unused supplies while active to do
without any per-driver code.
- DAPM widgets for DAIs, initially giving a speed boost for playback
startup and shutdown and also the basis for CODEC<->CODEC DAI link
support.
- Support for specifying the number of significant bits on audio
interfaces, useful for allowing applications to know how much effort
to put into generating data for a larger sample format.
- Conversion of the FSI driver used on some SH processors to
DMAEngine.
- Conversion of EP93xx drivers to DMAEngine.
- New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
WM2200.
- Move audmux driver from arc/arm to sound/soc
- McBSP move from arch/ to sound/ and updates
Also, a few small updates and fixes for other drivers like au88x0,
ymfpci, USB 6fire, USB usx2yaudio are included.

This is a partial revert of commit:
d40f833 "Restrict CFLAGS for hostprogs"
The endian-manipulation macros in tools/include need <linux/types.h>,
but the hostprogs in arch/x86/boot need several headers from the
kernel build tree, which means we have to add the kernel headers to
the include path. This picks up <linux/types.h> from the kernel tree,
which gives a warning.
Since this use of <linux/types.h> is intentional, add
-D__EXPORTED_HEADERS__ to the command line to silence the warning.
A better way to fix this would be to always install the exported
kernel headers into $(objtree)/usr/include as a standard part of the
kernel build, but that is a lot more involved.
