3b6456d2c3 zoran: don't bother with struct file * in zoran_map
all we need it for is file->private_data, which is assign-once, already
assigned by that point and, incidentally, its value is already in use
by zoran ->mmap() anyway.  So just store that pointer instead...

79714f72d3 get rid of kern_path_parent()
all callers want the same thing, actually - a kinda-sorta analog of
kern_path_create().  I.e. they want parent vfsmount/dentry (with
->i_mutex held, to make sure the child dentry is still their child)
+ the child dentry.

6b91bf1a3f drivers/rtc/rtc-twl.c: fix threaded IRQ to use IRQF_ONESHOT
Requesting a threaded interrupt without a primary handler and without
IRQF_ONESHOT is dangerous, and after commit 1c6c6952 ("genirq: Reject
bogus threaded irq requests"), these requests are rejected.  This causes
->probe() to fail, and the RTC driver not to be availble.

To fix, add IRQF_ONESHOT to the IRQ flags.

Tested on OMAP3730/OveroSTORM and OMAP4430/Panda board using rtcwake to
wake from system suspend multiple times.

8875408abd sgi-xp: nested calls to spin_lock_irqsave()
The code here has a nested spin_lock_irqsave().  It's not needed since
IRQs are already disabled and it causes a problem because it means that
IRQs won't be enabled again at the end.  The second call to
spin_lock_irqsave() will overwrite the value of irq_flags and we can't
restore the proper settings.

8a76e5383f media: mx2_camera: Fix mbus format handling
Do not use MX2_CAMERA_SWAP16 and MX2_CAMERA_PACK_DIR_MSB flags. The driver
must negotiate with the attached sensor whether the mbus format is UYUV or
YUYV and set CSICR1 configuration accordingly.

This is needed for the video function on mach-imx27_visstrim_m10.c to
perform properly, since an earlier version of this patch has been proven
wrong and has been reverted and a commit, depending on it: "[media]

Pull GPIO fixes from Linus Walleij:
 "Yes, this is a *LATE* GPIO pull request with fixes for v3.5.

  Grant moved across the planet and accidentally fell off the grid, so
  he asked me to take over the GPIO merges for a while 10 days ago.

  Since then I went over the archives and collected this pile of fixes,
  and pulled two of them from the TI maintainer Kevin Hilman.  Then
  waited for them to at least hit linux-next once or twice."

GPIO fixes for v3.5:
 - Invalid context restore on bank 0 for OMAP driver in runtime
   suspend/resume cycle
 - Check for NULL platform data in sta-2x11 driver
 - Constrain selection of the V1 MSM GPIO driver to applicable platforms
   (Kconfig issue)
 - Make sure the correct output value is set in the wm8994 driver
 - Export devm_gpio_request_one() so it can be used in modules.
   Apparently some in-kernel modules can be configured to use this
   leading to breakage.
 - Check that the GPIO is valid in the lantiq driver
 - Fix the flag bits introduced for v3.5, so they don't overlap
 - Fix a device tree intialization bug for imx21-compatible devices
 - Carry over the OF node to the TPS65910 GPIO chip struct

	    by leaving Bus Master Arbitration enabled.

The bug snuck back in in commit 2feec47d4c (ACPICA: ACPI 5: Support
for new FADT SleepStatus, SleepControl registers, 2012-02-14),
presumably by copy/pasting a copy of the code without that fix for the
legacy case.

On affected machines, after that commit, the machine locks up hard on
resume from suspend.  The same fix as seven years ago still works.

bc51b0c22c Revert "of: match by compatible property first"
This reverts commit 107a84e61c.

Meelis Roos reports a regression since 3.5-rc5 that stops Sun Fire V100
and Sun Netra X1 sparc64 machines from booting, hanging after enabling
serial console.  He bisected it to commit 107a84e61c.

Rob Herring explains:
 "The problem is match combinations of compatible plus name and/or type
  fail to match correctly.  I have a fix for this, but given how late it
  is for 3.5 I think it is best to revert this for now.  There could be
  other cases that rely on the current although wrong behavior.  I will
  post an updated version for 3.6."

dbf0e4c725 PCI: EHCI: fix crash during suspend on ASUS computers
Quite a few ASUS computers experience a nasty problem, related to the
EHCI controllers, when going into system suspend.  It was observed
that the problem didn't occur if the controllers were not put into the
D3 power state before starting the suspend, and commit
151b612847 (USB: EHCI: fix crash during
suspend on ASUS computers) was created to do this.

It turned out this approach messed up other computers that didn't have
the problem -- it prevented USB wakeup from working.  Consequently
commit c2fb8a3fa2 (USB: add
NO_D3_DURING_SLEEP flag and revert 151b612847) was merged; it
reverted the earlier commit and added a whitelist of known good board
names.

Now we know the actual cause of the problem.  Thanks to AceLan Kao for
tracking it down.

According to him, an engineer at ASUS explained that some of their
BIOSes contain a bug that was added in an attempt to work around a
problem in early versions of Windows.  When the computer goes into S3
suspend, the BIOS tries to verify that the EHCI controllers were first
quiesced by the OS.  Nothing's wrong with this, but the BIOS does it
by checking that the PCI COMMAND registers contain 0 without checking
the controllers' power state.  If the register isn't 0, the BIOS
assumes the controller needs to be quiesced and tries to do so.  This
involves making various MMIO accesses to the controller, which don't
work very well if the controller is already in D3.  The end result is
a system hang or memory corruption.

Since the value in the PCI COMMAND register doesn't matter once the
controller has been suspended, and since the value will be restored
anyway when the controller is resumed, we can work around the BIOS bug
simply by setting the register to 0 during system suspend.  This patch
(as1590) does so and also reverts the second commit mentioned above,
which is now unnecessary.

In theory we could do this for every PCI device.  However to avoid
introducing new problems, the patch restricts itself to EHCI host
controllers.

Finally the affected systems can suspend with USB wakeup working
properly.
