Y41x formats is a 4:4:4 format, so it can be addressed with pixel level accuracy.
Meanwhile it seems that while rotating YUYV 4:2:2 formats need a multiple of 2
for width and height, otherwise corruption occurs.
For YUV 4:2:2, the spec says that w/h should always be even, but we get
away with odd height while unrotated. When rotating it seems corruption
occurs with an odd x/y, and w/h should always be even.
Just to be completely paranoid, reject odd x/y w/h when rotating 90/270.

The intent was to expose these as part of the means to perform full
context recovery (though not the SINGLE_TIMELINE, that is for later and
just sucked as collateral damage). As that requires a couple more
patches to complete the series, roll back the earlier chunks of ABI for
an intervening PR. We keep all the internals intact and under selftests.

This is to disable semaphore usage when on vGPU for now. Unfortunately
GVT-g hasn't fully enabled semaphore usage yet, so current guest with
semaphore use would cause vGPU failure.
Although current semaphore failure with vGPU can be simply resolved by
allowing cmd parser to accept MI_SEMAPHORE_WAIT command with address
audit, we're checking general usage of semaphore and how we should
handle it properly for virtualization in consider of function and
security concern. So we decide to request to disable it for now in
guest driver. Once GVT could support it, we would add new compat bit
to turn it on.

Update the DP MSA MISC bits for fastsets. This is needed
when we change between limited and full range RGB output.
On HSW+ changing limited_range does not currently result in a
full modeset since we have don't have the readout code for it
(for DP we could, and probably should, readout from TRANS_MSA_MISC
itself, for HDMI we would have to rely on the infoframe). So
the PIPE_CONF_CHECK() is only performed for pre-HSW platforms.
That means any change in the value will result in a fastset
instead. Fortunately there is no prohibition to changing
TRANS_MSA_MISC dynamically, so it looks like we can legally do
fastsets for this.

Iterate over child devices instead of ports in parse_ddi_ports() to
initialize ddi_port_info. We'll eventually need to decide some stuff
based on the child device order, which may be different from the port
order.
As a bonus, this allows better abstractions for e.g. dvo port mapping.
There's a subtle change in the DDC pin and AUX channel sanitization as
we change the order. Otherwise, this should not change behaviour.

The AGPBUSY thing doesn't work on i945gm anymore. This means
the gmch is incapable of waking the CPU from C3 when an interrupt
is generated. The interrupts just get postponed indefinitely until
something wakes up the CPU. This is rather annoying for vblank
interrupts as we are unable to maintain a steady framerate
unless the machine is sufficiently loaded to stay out of C3.
To combat this let's use pm_qos to prevent C3 whenever vblank
interrupts are enabled. To maintain reasonable amount of powersaving
we will attempt to limit this to C3 only while leaving C1 and C2
enabled.

Since commit b7137e0cf1 ("drm/i915: Defer enabling rc6 til after we
submit the first batch/context"), intel_suspend_gt_powersave() has been
a no-op. As we still do not need to do anything explicitly on suspend
(we do everything required on idling), remove the defunct function.

Pull scheduler updates from Thomas Gleixner:
"Third more careful attempt for this set of fixes:
- Prevent a 32bit math overflow in the cpufreq code
- Fix a buffer overflow when scanning the cgroup2 cpu.max property
- A set of fixes for the NOHZ scheduler logic to prevent waking up
CPUs even if the capacity of the busy CPUs is sufficient along with
other tweaks optimizing the behaviour for asymmetric systems
(big/little)"

Pull perf updates from Thomas Gleixner:
"A larger set of perf updates.
Not all of them are strictly fixes, but that's solely the tip
maintainers fault as they let the timely -rc1 pull request fall
through the cracks for various reasons including travel. So I'm
sending this nevertheless because rebasing and distangling fixes and
updates would be a mess and risky as well. As of tomorrow, a strict
fixes separation is happening again. Sorry for the slip-up.
Kernel:
- Handle RECORD_MMAP vs. RECORD_MMAP2 correctly so different
consumers of the mmap event get what they requested.
Tools:
- A larger set of updates to perf record/report/scripts vs. time
stamp handling
- More Python3 fixups
- A pile of memory leak plumbing
- perf BPF improvements and fixes
- Finalize the perf.data directory storage"
[ Note: the kernel part is strictly a fix, the updates are purely to
tooling - Linus ]

"A set of x86 fixes:
- Prevent potential NULL pointer dereferences in the HPET and HyperV
code

crashes on access
- Use the correct macros for Cyrix I/O on Geode processors
- Remove yet another kernel address printk leak
- Announce microcode reload completion as requested by quite some
people. Microcode loading has become popular recently.
- Some 'Make Clang' happy fixlets

"A set of small fixes plus the removal of stale board support code:
- Remove the board support code from the clpx711x clocksource driver.
This change had fallen through the cracks and I'm sending it now
rather than dealing with people who want to improve that stale code
for 3 month.
