V4L2_PIX_FMT_AYUV32
V4L2_PIX_FMT_XYUV32
V4L2_PIX_FMT_VUYA32
V4L2_PIX_FMT_VUYX32
These formats enable the trasmission of alpha channel data to other
drivers and userspace applications in addition to YUV data. For
example, buffers generated by drivers in one of these formats
can be used by the Weston compositor to display as a texture or
flipped directly onto the overlay planes with the help of a DRM

The current dentry number tracking code doesn't distinguish between
positive & negative dentries. It just reports the total number of
dentries in the LRU lists.
As excessive number of negative dentries can have an impact on system
performance, it will be wise to track the number of positive and
negative dentries separately.
This patch adds tracking for the total number of negative dentries in
the system LRU lists and reports it in the 5th field in the
/proc/sys/fs/dentry-state file. The number, however, does not include
negative dentries that are in flight but not in the LRU yet as well as
those in the shrinker lists which are on the way out anyway.
The number of positive dentries in the LRU lists can be roughly found by
subtracting the number of negative dentries from the unused count.
Matthew Wilcox had confirmed that since the introduction of the
dentry_stat structure in 2.1.60, the dummy array was there, probably for
future extension. They were not replacements of pre-existing fields.
So no sane applications that read the value of /proc/sys/fs/dentry-state
will do dummy thing if the last 2 fields of the sysctl parameter are not
zero. IOW, it will be safe to use one of the dummy array entry for
negative dentry count.

Commit 765b6a98c1 ("iommu/vt-d: Enumerate the scalable
mode capability") enables VT-d scalable mode if hardware
advertises the capability. As we will bring up different
features and use cases to upstream in different patch
series, it will leave some intermediate kernel versions
which support partial features. Hence, end user might run
into problems when they use such kernels on bare metals
or virtualization environments.
This leaves scalable mode default off and end users could
turn it on with "intel-iommu=sm_on" only when they have
clear ideas about which scalable features are supported
in the kernel.

Turns out this is not such a great idea. Once the SP clock is disabled,
it's not sufficient to just enable in order to bring the SP core back up.
It seems that the kernel has no business managing this clock. Just let
the firmware keep it enabled.

The CSI controller found on the H3 (and H5) is a reduced version of the
one found on the A31. It only has 1 channel, instead of 4 channels for
time-multiplexed BT.656. Since the H3 is a reduced version, it cannot
"fallback" to a compatible that implements more features than it
supports.
Split out the H3 compatible as a separate entry, with no fallback.

The changes introduced to allow rxrpc calls to be retried creates an issue
when it comes to refcounting afs_call structs. The problem is that when
rxrpc_send_data() queues the last packet for an asynchronous call, the
following sequence can occur:
(1) The notify_end_tx callback is invoked which causes the state in the
afs_call to be changed from AFS_CALL_CL_REQUESTING or
AFS_CALL_SV_REPLYING.
(2) afs_deliver_to_call() can then process event notifications from rxrpc
on the async_work queue.
(3) Delivery of events, such as an abort from the server, can cause the
afs_call state to be changed to AFS_CALL_COMPLETE on async_work.
(4) For an asynchronous call, afs_process_async_call() notes that the call
is complete and tried to clean up all the refs on async_work.
(5) rxrpc_send_data() might return the amount of data transferred
(success) or an error - which could in turn reflect a local error or a
received error.
Synchronising the clean up after rxrpc_kernel_send_data() returns an error
with the asynchronous cleanup is then tricky to get right.
Mostly revert commit c038a58ccf. The two API
functions the original commit added aren't currently used. This makes
rxrpc_kernel_send_data() always return successfully if it queued the data
it was given.
Note that this doesn't affect synchronous calls since their Rx notification
function merely pokes a wait queue and does not refcounting. The
asynchronous call notification function *has* to do refcounting and pass a
ref over the work item to avoid the need to sync the workqueue in call
cleanup.

A bigger batch than I anticipated this week, for two reasons:
- Some fallout on Davinci from board file -> DTB conversion, that also
includes a few longer-standing fixes (i.e. not recent regressions).
- drivers/reset material that has been in linux-next for a while, but
didn't get sent to us until now for a variety of reasons (maintainer out
sick, holidays, etc). There's a functional dependency in there such that
one platform (Altera's SoCFPGA) won't boot without one of the patches;
instead of reverting the patch that got merged, I looked at this set
and decided it was small enough that I'll pick it up anyway. If you
disagree I can revisit with a smaller set.
That being said, there's also a handful of the usual stuff:
- Fix for a crash on Armada 7K/8K when the kernel touches PSCI-reserved
memory
- Fix for PCIe reset on Macchiatobin (Armada 8K development board, what
this email is sent from in fact :)
- Enable a few new-merged modules for Amlogic in arm64 defconfig
- Error path fixes on Integrator
- Build fix for Renesas and Qualcomm
- Initialization fix for Renesas RZ/G2E
+ A few more fixlets.

Here is one small sysfs change, and a documentation update for 5.0-rc2
The sysfs change moves from using BUG_ON to WARN_ON, as discussed in an
email thread on lkml while trying to track down another driver bug.
sysfs should not be crashing and preventing people from seeing where
they went wrong. Now it properly recovers and warns the developer.
The documentation update removes the use of BUS_ATTR() as the kernel is
moving away from this to use the specific BUS_ATTR_RW() and friends
instead. There are pending patches in all of the different subsystems
to remove the last users of this macro, but for now, don't advertise it
should be used anymore to keep new ones from being introduced.
Both have been in linux-next with no reported issues.
