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.

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.

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.

Without this patch, if Device Tree is enabled the AB8500 RTC wouldn't get
probed at all, as there is no reference to it from platform code. This

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.

- Make sure the correct output value is set in the wm8994 driver
- Export devm_gpio_request_one() so it can be used in modules.

presumably by copy/pasting a copy of the code without that fix for the

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

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."

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
151b61284776be2d6f02d48c23c3625678960b97 (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 c2fb8a3fa25513de8fedb38509b1f15a5bbee47b (USB: add
NO_D3_DURING_SLEEP flag and revert 151b61284776be2) 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.

The patch needs to be synchronized with the bcm5974 patch for

This bug has been present ever since data-check was introduce
in 2.6.16. However it would only fire if a data-check were
done on a degraded array, which was only possible if the array
has 3 or more devices. This is certainly possible, but is quite
uncommon.
Since hot-replace was added in 3.3 it can happen more often as
the same condition can arise if not all possible replacements are
present.
The problem is that as soon as we submit the last read request, the
'r1_bio' structure could be freed at any time, so we really should
stop looking at it. If the last device is being read from we will
stop looking at it. However if the last device is not due to be read
from, we will still check the bio pointer in the r1_bio, but the
r1_bio might already be free.
So use the read_targets counter to make sure we stop looking for bios
to submit as soon as we have submitted them all.
This fix is suitable for any -stable kernel since 2.6.16.

Since ee7cd8981e15bcb365fc762afe3fc47b8242f630 'virtio: expose added
descriptors immediately.', in virtio balloon virtqueue_get_buf might
now run concurrently with virtqueue_kick. I audited both and this
seems safe in practice but this is not guaranteed by the API.
Additionally, a spurious interrupt might in theory make
virtqueue_get_buf run in parallel with virtqueue_add_buf, which is
racy.
While we might try to protect against spurious callbacks it's
easier to fix the driver: balloon seems to be the only one
(mis)using the API like this, so let's just fix balloon.
