commit b6855772f4a22c4fbdd4fcaceff5c8a527035123 upstream.
ath5k assumes ah_current_channel is always a valid pointer in
several places, but a newly created interface may not have a
channel. To avoid null pointer dereferences, set it up to point
to the first available channel until later reconfigured.
This fixes the following oops:
$ rmmod ath5k
$ insmod ath5k
$ iw phy0 set distance 11000

commit bc9d24a3aeb1532fc3e234907a8b6d671f7ed68f upstream.
Before we mark the wireless device as unplugged, check PCI config space
to see whether the wireless device is really disabled (and vice versa).
This works around newer models which don't want the hotplug code, where
we end up disabling the wired network device.
My old 701 still works correctly with this. I can also simulate an
afflicted model by changing the hardcoded PCI bus/slot number in the
driver, and it seems to work nicely (although it is a bit noisy).
In future this type of hotplug support will be implemented by the PCI
core. The existing blacklist and the new warning message will be
removed at that point.

commit b561e8274f75831ee87e4ea378cbb1f9f050a51a upstream.
The flow id (scd_flow) in a compressed BA packet should match the txq_id
of the queue from which the aggregated packets were sent. However, in
some hardware like the 1000 series, sometimes the flow id is 0 for the
txq_id (10 to 19). This can cause the annoying message:
[ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected
[ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0),
index 5, is out of range [0-256] 7 7.
And even worse, if agg->wait_for_ba is true when the bad BA is arriving,
this can cause system hang due to NULL pointer dereference because the
code is operating in a wrong tx queue!

commit 806b07c29b711aaf90c81d2a19711607769f8246 upstream.
IR support on FusionHDTV cards is broken since kernel 2.6.31. One side
effect of the switch to the standard binding model for IR I2C devices
was to let i2c-core do the probing instead of the ir-kbd-i2c driver.
There is a slight difference between the two probe methods: i2c-core
uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As
some IR I2C devices only support reads, the new probe method fails to
detect them.
For now, revert to letting the driver do the probe, using 0-byte
reads. In the future, i2c-core will be extended to let callers of
i2c_new_probed_device() provide a custom probing function.

fix memory leak introduced by the patch 6e03a201bbe:
firmware: speed up request_firmware()
1. vfree won't release pages there were allocated explicitly and mapped
using vmap. The memory has to be vunmap-ed and the pages needs
to be freed explicitly
2. page array is moved into the 'struct
firmware' so that we can free it from release_firmware()
and not only in fw_dev_release()
The fix doesn't break the firmware load speed.

commit 380fefb2ddabd4cd5f14dbe090481f0544e65078 upstream.
dm9000_set_rx_csum and dm9000_hash_table are called from atomic context (in
dm9000_init_dm9000), and from non-atomic context (via ethtool_ops and
net_device_ops respectively). This causes a spinlock recursion BUG. Fix this by
renaming these functions to *_unlocked for the atomic context, and make the
original functions locking wrappers for use in the non-atomic context.

commit b6dacf63e9fb2e7a1369843d6cef332f76fca6a3 upstream.
The ACPI spec tells us that the firmware will reenable SCI_EN on resume.
Reality disagrees in some cases. The ACPI spec tells us that the only way
to set SCI_EN is via an SMM call.
https://bugzilla.kernel.org/show_bug.cgi?id=13745 shows us that doing so
may break machines. Tracing the ACPI calls made by Windows shows that it
unconditionally sets SCI_EN on resume with a direct register write, and
therefore the overwhelming probability is that everything is fine with
this behaviour.

commit 718be4aaf3613cf7c2d097f925abc3d3553c0605 upstream.
It turns out that there is a bit in the _CST for Intel FFH C3
that tells the OS if we should be checking BM_STS or not.
Linux has been unconditionally checking BM_STS.
If the chip-set is configured to enable BM_STS,
it can retard or completely prevent entry into
deep C-states -- as illustrated by turbostat:

commit 47f19c0eedb377ad1ee8114f464d001ec5f96a69 upstream.
When an attempt is made to read the interface strings of the Artisman
Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written
to the dmesg log (uhci_result_common: failed with status 440000) and the
dongle resets itself, resulting in a disconnect/reconnect loop.
Adding the dongle to the list of devices in quirks.c, with the same
quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D
joystick, stops the device from resetting and allows it to be used with
no problems.

commit 48826626263d4a61d06fd8c5805da31f925aefa0 upstream.
This patch (as1403) is a partial reversion of an earlier change
(commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote
wakeup settings during system sleep"). After hearing from a user, I
realized that remote wakeup should be enabled during system sleep
whenever userspace allows it, and not only if a driver requests it
too.
Indeed, there could be a device with no driver, that does nothing but
generate a wakeup request when the user presses a button. Such a
device should be allowed to do its job.
The problem fixed by the earlier patch -- device generating a wakeup
request for no reason, causing system suspend to abort -- was also
addressed by a later patch ("USB: don't enable remote wakeup by
default", accepted but not yet merged into mainline). The device
won't be able to generate the bogus wakeup requests because it will be
disabled for remote wakeup by default. Hence this reversion will not
re-introduce any old problems.

commit 3fea60261e73dbf4a51130d40cafcc8465b0f2c3 upstream.
The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c)
defines a key map for the matrix keypad keyboard. The hardware seems to
use all of the 8 rows and 8 columns of the keypad, although not all
possible locations are used.
The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys
are defined with a row and column number between 0 and 7, except
KEY(0xff, 2, KEY_F9),
KEY(0xff, 4, KEY_F10),
KEY(0xff, 5, KEY_F11),
which represent keycodes that should be emitted when entire row is
connected to the ground. since the driver handles this case as if we
had an extra column in the key matrix. Unfortunately we do not allocate
enough space and end up owerwriting some random memory.

Sumeet Lahorani <sumeet.lahorani@oracle.com> reported that the IPoIB
child entries are world-writable; however we don't want ordinary users
to be able to create and destroy child interfaces, so fix them to be
writable only by root.

System will crash sooner or later once the memory with the code of the
s3c-sdhci.ko module is reused for something else. I really have no idea
how the lack of remove function went unnoticed into the mainline code.

commit 96fc3a45ea073136566f3c2676cad52f8b39a7df upstream.
The ds1307 driver misreads the ds1388 registers when checking for 12 or 24
hour mode. Instead of checking the hour register it reads the minute
register. Therefore the driver thinks minutes >= 40 has the 12HR bit set
and resets the minute register by zeroing the high bits. This results in
minutes are reset to 0-9, jumping back in time 40 or 50 minutes. The time
jump is also written back to the RTC.

commit 720fc22a7af79d91ec460c80efa92c65c12d105e upstream.
When ide taskfile access is being used (for example with hdparm --security
commands) and cfq scheduler is selected, the scheduler crashes on BUG in
cfq_put_request.
The reason is that the cfq scheduler is tracking counts of read and write
requests separately; the ide-taskfile subsystem allocates a read request and
then flips the flag to make it a write request. The counters in cfq will
mismatch.
This patch changes ide-taskfile to allocate the READ or WRITE request as
required and don't change the flag later.

commit a9ddabc52ce3757a4331d6c1e8bf4065333cc51b upstream.
When implementing the test_iqr() method, I forgot that this driver is not an
ordinary PCI driver and also needs to support VLB variant of the chip. Moreover,
'hwif->dev' should be NULL, potentially causing oops in pci_read_config_byte().

commit 8cd774ad30c22b9d89823f1f05d845f4cdaba9e8 upstream.
The cpm_uart_early_write() function which was used for console poll
isn't implemented in the cpm uart driver.
Implementing this function both fixes the build when CONFIG_CONSOLE_POLL
is set and allows kgdboc to work via the cpm uart.

commit 6fd024893911dcb51b4a0aa71971db5ba38f7071 upstream.
The current initialisation code probes 'unsupported' AGP devices
simply by calling its own probe function. It does not lock these
devices or even check whether another driver is already bound to
them.
We must use the device core to manage this. So if the specific
device id table didn't match anything and agp_try_unsupported=1,
switch the device id table and call driver_attach() again.

commit 59f6fbe4291fcc078ba26ce4edf8373a7620a13a upstream.
Fix subsequent suspends by issuing tpm_continue_selftest during resume.
Otherwise, the tpm chip seems to be not fully initialized and will reject
the save state command during suspend, thus preventing the whole system
to suspend.

commit 688acaa2897462e4c5e2482496e2868db0760809 upstream.
Code did not handle projected 2d and depth coordinates, meaning potentially
set 3d or cube special handling might stick.
(Not sure what depth coord actually does, but I guess handling it
like a normal coordinate is the right thing to do.)

commit 6ba770dc5c334aff1c055c8728d34656e0f091e2 upstream.
Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC
reference clock.
More generally, the 0.488% tolerance used before is just too tight to
reliably find a PLL setting. I extracted the search algorithm and
modified it to find the dot clocks with maximum error over the valid
range for the given output type:
http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c
This gave:
Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571)
Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524)
Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488)
Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529)
Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488)
Worst dotclock for G4X SDVO refclk is 267600kHz (error 0.00448)
Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478)
Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449)
Worst dotclock for G4X DL-LVDS refclk is 224000kHz (error 0.00510)

commit 944001201ca0196bcdb088129e5866a9f379d08c upstream.
A lot of 945GMs have had stability issues for a long time, this manifested as X hangs, blitter engine hangs, and lots of crashes.
one such report is at:
https://bugs.freedesktop.org/show_bug.cgi?id=20560
along with numerous distro bugzillas.
This only took a week of digging and hair ripping to figure out.
Tracked down and tested on a 945GM Lenovo T60,
previously running
x11perf -copypixwin500
or
x11perf -copywinpix500
repeatedly would cause the GPU to wedge within 4 or 5 tries, with random busy bits set.
After this patch no hangs were observed.
