1f6ff364ce [SCSI] libfc: Pass lport in exch_mgr_reset
fc_exch_mgr structure is private to fc_exch.c. To export exch_mgr_reset to
transport, transport needs access to the exch manager. Change
exch_mgr_reset to use lport param which is the shared structure between
libFC and transport.

Alternatively, fc_exch_mgr definition can be moved to libfc.h so that lport
can be accessed from mp*.

The 'bytes' array is 64 bytes large but the easy standard programming

c9a0c8a684 [WATCHDOG] orion5x_wdt.c: 'ORION5X_TCLK' undeclared
orion5x_wdt no longer compiled after the changes in commit
ebe35aff88 ("Orion: prepare for
runtime-determined timer tick rate").

The tick rate define (ORION5X_TCLK) was removed in favor of a runtime
detection. The quick fix is to add the define in the watchdog driver.
The fix is not correct for all supported orion5x platforms, but since
the supported platforms right now are 133 Mhz and 166 Mhz, it won't
be _that_ far off. ;-) A fix that uses the runtime-determined timer
tick rate will be applied later.

968e594afd libata: Don't trust current capacity values in identify words 57-58
Hanno Böck reported a problem where an old Conner CP30254 240MB hard drive
was reported as 1.1TB in capacity by libata:

http://lkml.org/lkml/2009/2/13/134

This was caused by libata trusting the drive's reported current capacity in
sectors in identify words 57 and 58 if the drive does not support LBA and the
current CHS translation values appear valid. Unfortunately it seems older
ATA specs were vague about what this field should contain and a number of drives
used values with wrong byte order or that were totally bogus. There's no
unique information that it conveys and so we can just calculate the number
of sectors from the reported current CHS values.

While we're at it, clean up this function to use named constants for the
identify word values.

d6515e6ff4 libata: make sure port is thawed when skipping resets
When SCR access is available and the link is offline, softreset is
skipped as it only wastes time and some controllers don't respond very
well.  However, the skip path forgot to thaw the port, which not only
blocks further event notification from the port but also causes
repeated EH invocations on the same event on drivers which rely on
->thaw() to clear events if the IRQ is shared with another device or
port.

This problem has always been there but is uncovered by recent sata_nv
nf2/3 change which dropped hardreset support while maintaining SCR
access.  nf2/3 doesn't clear hotplug event mask from the interrupt
handler but relies on ->thaw() to clear them.  When the hardreset was
there, the reset action was never skipped and the port was always
thawed but, with the hardreset gone, ->prereset() determines that
there's no need for softreset and both ->softreset() and ->thaw() are
skipped.  This leads to stuck hotplug event in the IRQ status register
triggering hotplug event whenever IRQ is delieverd on the same IRQ.
As the controller shares the same IRQ for both ports, this happens on
every IO if one port is occpupied and the other isn't.

This patch fixes the problem by making sure that the port is thawed on
reset-skip path.

bko#11615 reports this problem.

DMA-mapping.txt says:

To unmap a scatterlist, just call:

	pci_unmap_sg(pdev, sglist, nents, direction);

Again, make sure DMA activity has already finished.

PLEASE NOTE:  The 'nents' argument to the pci_unmap_sg call must be
              the _same_ one you passed into the pci_map_sg call,
	      it should _NOT_ be the 'count' value _returned_ from the
              pci_map_sg call.

The following patch enables SMC911x support to work on the OMAP LDP
board.  Although the SMC911x driver will eventually be obsoleted, the
smsc911x patches are rather invasive for the -rc kernels.

Rather than risk destablising smsc911x, this simpler patch is preferred
to allow the network interface to work.

This is done by
1) Wake up lock waiters when we close the master file descriptor.
   Not when the master structure is removed, since the latter
   requires the waiters themselves to release the refcount on the
   master structure -> Deadlock.
2) Send a SIGTERM to all clients waiting for the lock.
   Normally these clients will get a SIGPIPE when the X server dies,
   but clients may also spin trying to grab the DRM lock, without

cac477e8f1 cdc_ether: add usb id for Ericsson F3507g
The Ericsson F3507g wireless broadband module provides a CDC Ethernet
compliant interface, but identifies it as a "Mobile Direct Line" CDC
subclass, thereby preventing the CDC Ethernet class driver from picking
it up.  This patch adds the device id to cdc_ether.c as a workaround.

Ericsson has provided a "class" driver for this device:
http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094
But closer inspection of that driver reveals that it adds little more
than duplication of code from cdc_ether.c.  See also

6709fe9a27 r8169: read MAC address from EEPROM on init (2nd attempt)
This is 2nd attempt to implement the initialization/reading of MAC address
from EEPROM. The first used PCI's VPD and there were some problems, some
devices are not able to read EEPROM content by VPD. The 2nd one uses direct
access to EEPROM through bit-banging interface and my testing results seem
to be much better.

I tested 5 systems each with different Realtek NICs and I didn't find any
problem. AFAIK Francois's NICs also works fine.

Original description:
This fixes the problem when MAC address is set by ifconfig or by
ip link commands and this address is stored in the device after
reboot. The power-off is needed to get right MAC address.
This is problem when Xen daemon is running because it renames the device
name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF.
After reboot the device is still using FE:FF:FF:FF:FF:FF.

3ecdb9acf3 USB: musb: be careful with 64K+ transfer lengths, host side
Feeding 32-bit length cast down to 'u16' to min() to calculate the FIFO
count in musb_host_tx() risks sending a short packet prematurely for
transfer sizes over 64 KB.

Similarly, although data transfer size shouldn't exceed 65535 bytes for
the control endpoint, making musb_h_ep0_continue() more robust WRT URBs
with possibly oversized buffer will not hurt either...

51d9f3e100 USB: musb: fix data toggle saving with shared FIFO
For some strange reason the host side musb_giveback() decides
that it's always got an IN transfer when the hardware endpoint
is using a shared FIFO.  This causes musb_save_toggle() to read
the toggle state from the RXCSR register instead of TXCSR, and
may also cause unneeded reloading of RX endpoint registers.

dc61d238b8 USB: musb: host endpoint_disable() oops fixes
The musb_h_disable() routine can oops in some cases:

 - It's not safe to read hep->hcpriv outside musb->lock,
   since it gets changed on completion IRQ paths.

 - The list iterators aren't safe to use in that way;
   just remove the first element while !list_empty(),
   so deletions on other code paths can't make trouble.

We need two "scrub the list" loops because only one branch
should touch hardware and advance the schedule.

a2fd814e6a USB: musb: fix urb_dequeue() method
The urb_dequeue() method forgets to unlink 'struct musb_qh' from the
control or bulk schedules when the URB being cancelled is the only
one queued to its endpoint.  That will cause musb_advance_schedule()
to block once it reaches 'struct musb_qh' with now empty URB list, so
URBs queued for other endpoints after the one being dequeued will not
be served.

Fix by unlinking the QH from the list except when it's already being
handled (typically by musb_giveback).  Since a QH with an empty URB
list is now supposed to be freed, do that.  And remove a now-useless
check from musb_advance_schedule().

Shared FIFOs are most often configured for periodic endpoints,

34f32c9701 usb: musb: make Davinci *work* in mainline
Now that the musb build fixes for DaVinci got merged (RC3?), kick in
the other bits needed to get it finally *working* in mainline:

 - Use clk_enable()/clk_disable() ... the "always enable USB clocks"
   code this originally relied on has since been removed.

 - Initialize the USB device only after the relevant I2C GPIOs are
   available, so the host side can properly enable VBUS.

 - Tweak init sequencing to cope with mainline's relatively late init
   of the I2C system bus for power switches, transceivers, and so on.

Sanity tested on DM6664 EVM for host and peripheral modes; that system
won't boot with CONFIG_PM enabled, so OTG can't yet be tested.  Also
verified on OMAP3.

(Unrelated:  correct the MODULE_PARM_DESC spelling of musb_debug.)

67f5a4ba97 USB: usb_get_string should check the descriptor type
This patch (as1218) fixes a problem with a radio-control joystick used
in the "walkera 4#3" helicopter.  This device responds to the initial
Get-String-Descriptor request for string 0 (which is really the list
of supported languages) by sending its config descriptor!  The
usb_get_string() routine needs to check whether it got the right
type of descriptor.

Oddly enough, this sort of check is already present in
usb_get_descriptor().  The patch changes the error code from -EPROTO
to -ENODATA, because -EPROTO shows up in so many other contexts to
indicate a hardware failure rather than a firmware error.

9aa09d2f8f USB: EHCI: slow down ITD reuse
Currently ITDs are immediately recycled whenever their URB completes.
However, EHCI hardware can sometimes remember some ITD state.  This
means that when the ITD is reused before end-of-frame it may sometimes
cause the hardware to reference bogus state.

This patch defers reusing such ITDs by moving them into a new ehci member
cached_itd_list. ITDs resting in cached_itd_list are moved back into their
stream's free_list once scan_periodic() detects that the active frame has
elapsed.

This makes the snd_usb_us122l driver (in kernel since .28) work right
when it's hooked up through EHCI.

2) This fixes a bug where the device will come up with the enable-bit

It's safe to call ssb_pcicore_dev_irqvecs_enable() unconditionally, because
it has internal checks for redundant calls.

This fixes problems where hardware will not come up properly
due to quirks in the enable-bit hardware.

382c5546d6 V4L/DVB (10694): [PATCH] software IRQ watchdog for Flexcop B2C2 DVB PCI cards
With (some) Technisat cards you cannot run multiple DVB applications
in parallel and switch the channel at the same time.

There seems to be a problem on the interfaces or even inside the flexcop-device
that can't handle interruption on the streaming interface.

This patch adds a watchdog to check whether data is supposed to come in
(streaming PIDs are requested) and if no data is seen within 400ms (default) it
resets the streaming/pid-filtering hardware.

This patch is urgently needed to support the rev 2.8 of the hardware and solves
problem occassionally seen on older hardware.

7662b00c37 V4L/DVB (10659): em28xx: register device to soundcard for sysfs
As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should
set the struct device for the card before registering the card instance.
This will add the correct /sys/class/sound/cardN/device symlink, so HAL
can see the device and ConsoleKit sets its ACL permissions for the
logged-in user.

For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2),
this patch fixes errors like:

ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card

It needs to happen before any firewire driver actually registers itself,

But now there are firewire drivers in drivers/media, and the Makefile
games aren't enough.  So just make ieee1394_init happen earlier in the
init sequence, the way all other bus layers already do.

a760a6656e crypto: api - Fix module load deadlock with fallback algorithms
With the mandatory algorithm testing at registration, we have
now created a deadlock with algorithms requiring fallbacks.
This can happen if the module containing the algorithm requiring
fallback is loaded first, without the fallback module being loaded
first.  The system will then try to test the new algorithm, find
that it needs to load a fallback, and then try to load that.

As both algorithms share the same module alias, it can attempt
to load the original algorithm again and block indefinitely.

As algorithms requiring fallbacks are a special case, we can fix
this by giving them a different module alias than the rest.  Then
it's just a matter of using the right aliases according to what
algorithms we're trying to find.

6be96ac15e sata_mv: fix SoC interrupt breakage
For some reason, sata_mv doesn't clear interrupt status during init
when it's running on an SoC host adapter.  If the bootloader has
touched the SATA controller before starting Linux, Linux can end up
enabling the SATA interrupt with events pending, which will cause the
interrupt to be marked as spurious and then be disabled, which then
breaks all further accesses to the controller.

This patch makes the SoC path clear interrupt status on init like in
the non-SoC case.

7ba07d16bd pata_it821x: resume from hibernation fails with RAID volume
Hibernation didn't work for me since I started to use IT8212 controller.
I did some debugging (booting with no_console_suspend init=/bin/sh).

Found that resume fails (2.6.28) with "serial number mismatch 'some
garbage' != 'some other garbage'" and "revalidation failed" messages.
That's because the controller firmware fills different serial number in
the IDENTIFY every boot.

The patch below fixes the resume simply clearing the serial number.  The
proper fix would be probably to fill in the serial number of the RAID
volume instead.  I assume that there must be something like that stored on
the drives but I don't know where.

Fix resume on pata_it821x RAID volume by clearing the serial number in
IDENTIFY data, which is otherwise different on each boot.

[ The bug went unnoticed because after PIO/DMA timings get programmed

73d5c38a95 md: avoid races when stopping resync.
There has been a race in raid10 and raid1 for a long time
which has only recently started showing up due to a scheduler changed.

When a sync_read request finishes, as soon as reschedule_retry
is called, another thread can mark the resync request as having
completed, so md_do_sync can finish, ->stop can be called, and
->conf can be freed.  So using conf after reschedule_retry is not
safe.

Similarly, when finishing a sync_write, calling md_done_sync must be
the last thing we do, as it allows a chain of events which will free
conf and other data structures.

The first of these requires action in raid10.c
The second requires action in raid1.c and raid10.c

78200d45cd md/raid10: Don't call bitmap_cond_end_sync when we are doing recovery.
For raid1/4/5/6, resync (fixing inconsistencies between devices) is
very similar to recovery (rebuilding a failed device onto a spare).
The both walk through the device addresses in order.

For raid10 it can be quite different.  resync follows the 'array'
address, and makes sure all copies are the same.  Recover walks
through 'device' addresses and recreates each missing block.

The 'bitmap_cond_end_sync' function allows the write-intent-bitmap
(When present) to be updated to reflect a partially completed resync.
It makes assumptions which mean that it does not work correctly for
raid10 recovery at all.

In particularly, it can cause bitmap-directed recovery of a raid10 to
not recovery some of the blocks that need to be recovered.

So move the call to bitmap_cond_end_sync into the resync path, rather
than being in the common "resync or recovery" path.

09b4068a7f md/raid10: Don't skip more than 1 bitmap-chunk at a time during recovery.
When doing recovery on a raid10 with a write-intent bitmap, we only
need to recovery chunks that are flagged in the bitmap.

However if we choose to skip a chunk as it isn't flag, the code
currently skips the whole raid10-chunk, thus it might not recovery
some blocks that need recovering.

This patch fixes it.

In case that is confusing, it might help to understand that there
is a 'raid10 chunk size' which guides how data is distributed across
the devices, and a 'bitmap chunk size' which says how much data
corresponds to a single bit in the bitmap.

This bug only affects cases where the bitmap chunk size is smaller
than the raid10 chunk size.

cd97f39b7c i2c-dev: Clarify the unit of ioctl I2C_TIMEOUT
The unit in which user-space can set the bus timeout value is jiffies
for historical reasons (back when HZ was always 100.) This is however
not good because user-space doesn't know how long a jiffy lasts. The
timeout value should instead be set in a fixed time unit. Given the
original value of HZ, this unit should be 10 ms, for compatibility.

The PCIe port driver currently sets the PCIe AER error reporting bits for
any root or switch port without first checking to see if firmware will grant
control. This patch moves setting these bits to the AER service driver
aer_enable_port routine.  The bits are then set for the root port and any
downstream switch ports after the check for firmware support (aer_osc_setup)
is made. The patch also unsets the bits in a similar fashion when the AER
service driver is unloaded.

    Logging can be enabled with

    1 instead of -1 enables only FCP header logging,
    2 instead of -1 enables only hexdumps of the entire FCP frames.
    0 switches logging off again.

firedtv: register input device as child of a FireWire device

    Instead of one virtual input device which exists for the whole lifetime
    of the driver and receives events from all connected FireDTVs, register
    one input device for each firedtv device.  These input devices will show
    up as children of the respective firedtv devices in the sysfs hierarchy.

    However, the implementation falls short because of a bug in userspace:
    Udev's path_id script gets stuck with 100% CPU utilization, maybe
    because of an assumption about the maximum ieee1394 device hierarchy
    depth.

    To avoid this bug, we use the fw-host device instead of the proper
    unit_directory device as parent of the input device.

    There is hope that the port to the new firewire stack won't be inhibited
    by this userspace bug because there are no fw-host devices there.

firedtv: fix initialization of dvb_frontend.ops

    There was a NULL pointer reference if no dvb_frontend_info was found.

    Also, don't directly assign struct typed values to struct typed
    variables.  Instead write out assignments to individual strcut members.
    This reduces module size by about 1 kB.

firedtv: remove unused dual subunit code from initialization

    No FireDTVs with more than one subunit exists, hence simplify the
    initialization for the special case of one subunit.  The driver was able
    to check for more than one subunit but was broken for more than two
    subunits.

    While we are at it, add several missing cleanups after failure, and
    include a few dynamically allocated structures diretly into struct
    firesat instead of allocating them separately.

firedtv: add vendor_id and version to driver match table

    Now that nodemgr was enhanced to match against the root directory's
    vendor ID if there isn't one in the unit directory, use this to
    prevent firedtv to be bound to wrong devices by accident.

    Also add the AV/C software version ID to the match flags for
    completeness; specifier ID and software only make sense as a pair.

9c939e4df4 ieee1394: inherit ud vendor_id from node vendor_id
While Module_Vendor_ID in the configuration ROM's root directory is
mandatory, there often aren't vendor IDs in unit directories.  This
affects the new firedtv driver which is meant to be auto-loaded and
matched only for vendor-specific devices.

We now always copy ne->vendor_id into ud->vendor_id before we scan a
unit directory (and fill in a possibly present vendor ID from there).
This way, the root directory's vendor ID is used as fallback in the
"uevent" environment for modprobe'ing per module alias when a node was
plugged in, and in the driver match routine when protocol drivers are
bound to unit directories.  It will however not be used as sysfs
attribute of a unit directory device.

b33fdd6ca5 ieee1394: add hpsb_node_read() and hpsb_node_lock()
These will be used by the firedtv driver.  Like hpsb_node_write() they
are much better APIs for high-level drivers than hpsb_write() and its
siblings --- easier to use correctly and also terser.

Unlike hspb_node_write(), the two new functions will only be used by
one call site.  Hence make them static inline instead of exported
symbols.

29f8ea8ab0 ieee1394: use correct barrier types between accesses of nodeid and generation
A compiler barrier (explicit on the read side, implicit on the write
side) is not quite enough for what has to be accomplished here.  Use
hardware memory barriers on systems which need them.

(Of course a full fix of generation handling would require much more
than this.  The ieee1394 core's bus generation counter had to be tied to
the controller's bus generation counter; cf. Kristian's stack.  It's
just that I have other current business with the code around these
barrier()s, so why not do at least this small fix.)

Combination of the following changes:

Tue, 26 Aug 2008 00:17:30 +0200 (CEST)
firedtv: fix remote control input

    and update the scancode-to-keycode mapping to a current model.  Per
    default, various media key keycodes are emitted which closely match what
    is printed on the remote.  Userland can modify the mapping by means of
    evdev ioctls.  (Not tested.)

    The old scancode-to-keycode mapping is left in the driver but cannot be
    modified by ioctls.  This preserves status quo for old remotes.

firedtv: replace semaphore by mutex

    firesat->avc_sem and ->demux_sem have been used exactly like a mutex.
    The only exception is the schedule_remotecontrol tasklet which did a
    down_trylock in atomic context.  This is not possible with
    mutex_trylock; however the whole remote control related code is
    non-functional anyway at the moment.  This should be fixed eventually,
    probably by turning the tasklet into a worqueue job.

    Convert everything else from semaphore to mutex.

    Also rewrite a few of the affected functions to unlock the mutex at a
    single exit point, instead of in several branches.

df4846c352 firesat: update isochronous interface, add CI support
I have finally managed to get the CI support for the card working. The
implementation is a bare minimum to get encrypted channels to work in
kaffeine. It works fine with my T/CI card. Now and then I get an AVC
timeout and have to retune a channel in order to get it to work. Once
the CAM seemed to hang so I needed to remove and insert it again. I.e.
there are a number of glitches.

The latest version contains the following changes:

  - Implemented the new hpsb iso interface so that data can be received
    from the card
  - Reduced some timers for demux setup which caused scanning to timeout
  - Added possibility to unload driver
  - Added support for getting C/N ratio
  - Added two debug parameters to the driver; ca_debug and
    avc_comm_debug.
  - Added CI support that works for me in kaffeine
  - Started working on CI MMI support. It now supports:
      o Enter menu
      o Receiving MMI objects
  - Added support for 64-bit platforms
  - Corrected DVB-C modulations problems

In the KMS case, we need to suspend/resume GEM as well.  So on suspend, make

efbeed96f7 drm/i915: Don't let a device flush to prepare buffers clear new write_domains.
The problem was that object_set_to_gpu_domain would set the new write_domains
that are getting set by this batchbuffer, then the accumulated flushes required
for all the objects in preparation for this batchbuffer were posted, and the
brand new write domain would get cleared by the flush being posted.  Instead,
hang on to the new (or old if we're not changing it) value and set it after
the flush is queued.

Results from this noticably included conformance test failures from reads
shortly after writes (where the new write domain had been lost and thus not
flushed and waited on), but is a suspected cause of hangs in some apps when
a write domain is lost on a buffer that gets reused for instruction or
commmand state.

8cfd9e923b [ARM] RiscPC: Fix etherh oops
The 8390 driver was structured by Al Viro to allow the flexibility
required by platforms.  lib8390.c contains the core code which drivers
explicitly include:
- 8390.c includes lib8390.c to provide the standard ISA based driver.
- etherh.c includes it with the accessors defined for RiscPC platforms,
  where it is addressed via the MMIO accessors with a device dependent
  register spacing.

Other platform drivers do something similar.

However, b9a9b4b caused the kernel to contain not only the etherh
private build of lib8390 (included in etherh.c) but also lib8390.c
itself, and referred the new net_device_ops methods to the ISA version.
The result of this is is not pretty:

Unable to handle kernel paging request at virtual address 12032030

4898c2b2f0 fujitsu-laptop: Use RFKILL support bitmask from firmware
Up until now, we polled the rfkill status for every incoming FUJ02E3 ACPI event.
It turns out that the firmware has a bitmask which indicates what rfkill-related
state it can report.
The rfkill_supported bitmask is now used to avoid polling for rfkill at all in
the notification handler if there is no support. Also, it is used in the platform
device callbacks. As before we register all callbacks and report "unknown" if the
firmware does not give us status updates for that particular bit.

This was fed through checkpatch.pl and tested on the S6420, S7020 and P8010
platforms.

b6adea334c 8250: fix boot hang with serial console when using with Serial Over Lan port
Intel 8257x Ethernet boards have a feature called Serial Over Lan.

This feature works by emulating a serial port, and it is detected by
kernel as a normal 8250 port.  However, this emulation is not perfect, as
also noticed on changeset 7500b1f602.

Before this patch, the kernel were trying to check if the serial TX is
capable of work using IRQ's.

This were done with a code similar this:

        serial_outp(up, UART_IER, UART_IER_THRI);
        lsr = serial_in(up, UART_LSR);
        iir = serial_in(up, UART_IIR);
        serial_outp(up, UART_IER, 0);

        if (lsr & UART_LSR_TEMT && iir & UART_IIR_NO_INT)
		up->bugs |= UART_BUG_TXEN;

This works fine for other 8250 ports, but, on 8250-emulated SoL port, the
chip is a little lazy to down UART_IIR_NO_INT at UART_IIR register.

Due to that, UART_BUG_TXEN is sometimes enabled.  However, as TX IRQ keeps
working, and the TX polling is now enabled, the driver miss-interprets the
IRQ received later, hanging up the machine until a key is pressed at the
serial console.

This is the 6 version of this patch.  Previous versions were trying to
introduce a large enough delay between serial_outp and serial_in(up,
UART_IIR), but not taking forever.  However, the needed delay couldn't be
safely determined.

At the experimental tests, a delay of 1us solves most of the cases, but
still hangs sometimes.  Increasing the delay to 5us was better, but still
doesn't solve.  A very high delay of 50 ms seemed to work every time.

However, poking around with delays and pray for it to be enough doesn't
seem to be a good approach, even for a quirk.

So, instead of playing with random large arbitrary delays, let's just
disable UART_BUG_TXEN for all SoL ports.

196b7e1b9c smsc9420: handle magic field of ethtool_eeprom
ethtool.h says the driver should set the magic field in get_eeprom and
verify it in set_eeprom.  This patch adds this functionality using an
arbitary driver-specific magic value constant (0x9420).

9df8f4e3ee smsc9420: fix another postfixed timeout
Roel Kluin recently fixed several instances where variables reach -1,
but 0 is tested afterwards.  This patch fixes another, so the timeout
will be correctly detected and a warning printed.

494ef10eba wimax/i2400m: driver loads firmware v1.4 instead of v1.3
This is a one liner change to have the driver use by default the v1.4
of the i2400m firmware instead of v1.3. The v1.4 version of the
firmware has been submitted to David Woodhouse for inclusion in the
linux-firmware tree and it is already available at
http://linuxwimax.org/Download.

The reason for this change is that the 1.3 release of the user space
software and firmware has a few issues that will make it difficult to
use with currently deployed commercial networks such as Xohm and
Clearwire.

As well, the new 1.4 release of the user space software (which matches
the 1.4 firmware) has intermitent issues with the 1.3 firmware.

The 1.4 release in http://linuxwimax.org/Download has been widely
deployed and tested with the codebase in 2.6.29-rc, the 1.4 firmware
and the 1.4 user space components.

We understand it is quite late in the rc process for such a change,
but would like to ask for the change to be taken into consideration.

Alternatively, a user could always force feed a 1.4 firmware into a
driver that doesn't have this modification by:

$ cd /lib/firmware
$ mv i2400m-fw-usb-1.3.sbcf i2400m-fw-usb-1.3.real.sbcf
$ ln -sf i2400m-fw-usb-1.4.sbc i2400m-fw-usb-1.3.sbcf

This fixes potential fault at fault time if the object was unreferenced
while the mapping still existed.  Now, while the mmap_offset only lives
for the lifetime of the object, the object also stays alive while a vma
exists that needs it.

67eabc0553 drm/i915: Don't add panel_fixed_mode to the probed modes list at LVDS init.
In the case where no EDID data is read from the device, adding the
panel_fixed_mode pointer to the probed modes list causes data corruption.

If the panel_fixed_mode pointer is added to the probed modes list at
init time, a copy of the mode is added again at drm_get_modes() request
time.  Then, the panel_fixed_mode pointer is freed because it is seen as
a duplicate mode.  Unfortunately, this pointer is still stored and used
in mode_fixup().

Because the panel_fixed_mode data is copied and returned at
drm_get_modes() time, it is unnecessary to add this information at init
time.
