V4L/DVB (5887): zr36067: Fix poll() operation
During uncompressed capture, the poll() function was looking the wrong frame.
It was using the frame the driver was going to capture into next (pend_tail),
when it should have been looking at the next frame to be de-queued with
DQBUF/SYNC (sync_tail).
It also wasn't looking in the right spot. It was looking at the file handle's
copy of the buffer status, rather than the driver core copy. The interrupt
routine marks frames as done in the driver core copy, the file handle copy
isn't updated. So even if poll() looked at the right frame, it would never
see it transition to done and return POLLIN.
The compressed capture code has this same problem, looking in fh->jpg_buffers
when it should have used zr->jpg_buffers.
There was some logic to detect when there was no current capture in process
nor any frames queued and try to return an error, which ends up being a bad
idea. It's possible to call select() from one thread while no capture is in
process, or no frames queued, and then start a capture or queue frames from
another thread.
The buffer state variables are protected by a spin lock, which the code wasn't
acquiring. That is fixed too.

V4L/DVB (5886): zr36067: Fix problem setting norms
The zr36067 driver doesn't make a distinction between the different sub-types
of NTSC, PAL, or SECAM norms. For example, when the enum std ioctl returns
the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I.
When setting the norm, it required the bitmask to match exactly the set of
norms used during the enumeration. If just one norm was specified, for
example PAL_BG or NTSC_M, it would fail. This violates the V4L2 spec,
"VIDIOC_S_STD accepts *one* or more flags..."
The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple
bits. It's ok to call S_STD with any *one* of those bits, but the driver was
requiring *all* of them.
This fixes the S_STD function so that it will accept any set of one or more
PAL norms as PAL, and the same for NTSC and SECAM.

Also, introduce CONFIG_PM_SLEEP which is automatically selected if

The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the

[SCSI] aacraid: fix Sunrise Lake reset handling
The patch is *much* smaller than the description. I am attempting to
answer to those that want to understand an issue that was reported in
May this year.
If a Sunrise Lake based card that requires an alternate reset mechanism
is set up to ignore the commanded IOP_RESET it reports 0x00000010
(IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism
to reset all cores), and thus the reset platform function decides to
switch to IOP_RESET_ALWAYS because the reset platform function
parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS
then responds with the 0x3803000F return code, but alas we treat this as
an error instead of using the alternate reset mechanism (put a 0x03 into
the register offset 0x38). The reset fails, but the fact that the
IOP_RESET_ALWAYS command was issued has put the card in a purposeful
shutdown state in preparation for the alternate hardware reset to be
applied. Yuck.
IOP_RESET is ignored in internal production cards, typically to ensure
that we catch all adapter lockup issues without the driver progressing
further, so this would not appear to be a field issue and thus this
patch was destined to be only in the internal Adaptec source tree.
IOP_RESET_ALWAYS is reserved for
kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as
expected in any case. Also in the past we have had OEMs specifically
request that cards not be resetable after a BlinkLED/FirmwareAssert for
one reason or another and To head off the possibility that the Sunrise
Lake based cards would suffer a similar fate, we propose the enclosed
fix.
Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when
he reported an issue to the linux kernel list back in May regarding a
kexec problem resulting from this reset being ignore. His fix was to
update the Firmware to one that did not ignore the IOP_RESET. Previous
kernels did not attempt to reset the adapter and that is why it surfaced
as a regression in his hands.

Customer running an application that issues SYNCHRONIZE_CACHE calls

SYNCHRONIZE_CACHE call that would associate more tightly with the

[IA64] Fix build failure in fs/quota.c
b716395e2b8e450e294537de0c91476ded2f0395 added code to handle
a compatability issue with 32bit quota tools, but the new compat
routines are only needed when CONFIG_COMPAT=y (and with this set
to 'n' there are compilation problems since some new typedefs are
not visible).

Wide transfers are required for every setting of PPR apart from QAS.
It seems the DV code starts at the minimum, which turns on DT and Wide

setting routines to respect max_width (i.e. start at period = 10 if it

[S390] Fix IRQ tracing.
If a machine check is pending and the external or I/O interrupt handler
returns to userspace io_mcck_pending is going to call s390_handle_mcck.
Before this happens a call to TRACE_IRQS_ON was already made since we
know that we are going back to userspace and hence interrupts will be
enabled. So there was an indication that interrupts are enabled while
in reality they are still disabled.
s390_handle_mcck will do a local_irq_save/restore pair and confuse
lockdep which later complains about inconsistent irq tracing.
To solve this just call trace_hardirqs_off before calling
s390_handle_mcck and trace_hardirqs_on afterwards.
