If we hold a delegation then we know that it should be safe to continue
to cache the data beyond the close(). However since the process that wrote
the data may die after close(), we may still want to send the data to
server before those RPCSEC_GSS credentials expire. We therefore compromise
by starting writeback to the server, but don't wait for completion.

configuration bit in the preview engine update attributes table is set
to -1 to reflect that. However, the VIDIOC_OMAP3ISP_PRV_CFG ioctl

erroneously considers that the parameter has been selected for update by

When propagating the frame number through the pipeline, the frame number

was properly handled for the CSI2 and CCP2 receivers, but not when the
CCDC parallel interface is used.
ADD frame number incrementation to the HS/VS interrupt handler. As the
HS/VS interrupt is also generated for frames received by the CSI2 and
CCP2 receivers, remove explicit propagation handling from the serial
receivers.

The OMAP3 ISP preview engine will violate the L4 bus protocol if we try
to write some of its internal registers after it failed to stop
properly. This generates an external abort on non-linefetch fault,
triggering a fatal kernel oops.
We can't always prevent preview engine stop failures (they can for
instance be caused by a sensor crash), but we can improve the system
reliability by refusing to start streaming on a pipeline that contains
the preview engine if it failed to stop. The driver will then eventually
reset the ISP (when all applications will have closed their file handles
related to OMAP3 ISP device nodes), making the ISP usable again.

With the embed percpu first chunk allocator, x86 uses either PAGE_SIZE
or PMD_SIZE for atom_size. PMD_SIZE is used when CPU supports PSE so
that percpu areas are aligned to PMD mappings and possibly allow using
PMD mappings in vmalloc areas in the future. Using larger atom_size
doesn't waste actual memory; however, it does require larger vmalloc
space allocation later on for !first chunks.
With reasonably sized vmalloc area, PMD_SIZE shouldn't be a problem
but x86_32 at this point is anything but reasonable in terms of
address space and using larger atom_size reportedly leads to frequent
percpu allocation failures on certain setups.
As there is no reason to not use PMD_SIZE on x86_64 as vmalloc space
is aplenty and most x86_64 configurations support PSE, fix the issue
by always using PMD_SIZE on x86_64 and PAGE_SIZE on x86_32.
v2: drop cpu_has_pse test and make x86_64 always use PMD_SIZE and
x86_32 PAGE_SIZE as suggested by hpa.

Currently, the register prefixes in the driver seem to be mixed: the
capability registers are the ones that contain capability information,
such as number of hardware endpoints, while the registers that are
used to program the controller are called operational registers.
Normally, capability registers start at 0x100 offset of the register
window and are followed by operational registers. In some versions,
however, capability registers start at 0x0 offset.
This patch renames the register and adjusts their offsets appropriately,
leaving the possibility of having a non-standard capability offset.
I couldn't find any mentions of the TESTMODE register anywhere, so I
suspect it might only be enabled in chipidea internal versions of the
controller and I'm really inclined to remove it from the driver or at
least hiding it behind a config option.

This is a fix for the problem in commit 785f857d1c, the pop noise
issue on some machines with ALC269. The problem was the uninitialized
state after the resume due to the delayed resume of the codec chips.
In that commit, we tried to fix by forcibly putting the codec to D3 at
suspend. But, this still also leaves the uninitialized state after
resume, and it _might_ be still problematic with some BIOS. Since the
commit turned out to regress another issues, we reverted it in the
end.
Now, in this fix, try to fix by turning on the codec immediately at
the resume path. We need to take care of the power-saving in this
case. When the device is woken up at the power-saved state, it should
go power-saving again after the resume.
