The DU driver handles non-visible planes (fully clipped by the display's
boundaries) by considering them as disabled. It thus disables the plane
at the hardware level when the plane is moved off-screen. However, if
the plane was previously disabled and is non-visible when it gets
enabled, the attempt to disable it crashes, as the plane wasn't
previously enabled. Fix it.

When creating a frame buffer, the driver verifies that the pitches for
the chroma planes match the luma plane. This is done incorrectly for
fully planar YUV formats, without taking horizontal subsampling into
account. Fix it.

The DT example erronously uses the "renesas,r8a7795-dw-hdmi", when the
correct value is "renesas,r8a7795-hdmi". It is furthermore missing the
generic "renesas,rcar-gen3-hdmi" compatible string. Fix it.

a handful of fixes for OMAP, including a fix for DSI (display) on omap5.

Here are a number of small driver fixes for 5.9-rc5
Included in here are:
- habanalabs driver fixes
- interconnect driver fixes
- soundwire driver fixes
- dyndbg fixes for reported issues, and then reverts to fix it
all up to a sane state.
- phy driver fixes
Full details of these are in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

This code was missing and was forcing the L2 run with L1's msr

Currently code in svm_set_nested_state copies the current vmcb control
area to L1 control area (hsave->control), under assumption that
it mostly reflects the defaults that kvm choose, and later qemu
overrides these defaults with L2 state using standard KVM interfaces,
like KVM_SET_REGS.
However nested GIF (which is AMD specific thing) is by default is true,
and it is copied to hsave area as such.
This alone is not a big deal since on VMexit, GIF is always set to false,
regardless of what it was on VM entry. However in nested_svm_vmexit we
were first were setting GIF to false, but then we overwrite the control
fields with value from the hsave area. (including the nested GIF field
itself if GIF virtualization is enabled).
Now on normal vm entry this is not a problem, since GIF is usually false
prior to normal vm entry, and this is the value that copied to hsave,
and then restored, but this is not always the case when the nested state
is loaded as explained above.
To fix this issue, move svm_set_gif after we restore the L1 control
state in nested_svm_vmexit, so that even with wrong GIF in the
saved L1 control area, we still clear GIF as the spec says.

A build failure was raised by kbuild with the following error.
drivers/android/binder.c: Assembler messages:
drivers/android/binder.c:3861: Error: unrecognized keyword/register name `l.lwz ?ap,4(r24)'
drivers/android/binder.c:3866: Error: unrecognized keyword/register name `l.addi ?ap,r0,0'
The issue is with 64-bit get_user() calls on openrisc. I traced this to
a problem where in the internally in the get_user macros there is a cast
to long __gu_val this causes GCC to think the get_user call is 32-bit.
This binder code is really long and GCC allocates register r30, which
triggers the issue. The 64-bit get_user asm tries to get the 64-bit pair
register, which for r30 overflows the general register names and returns
the dummy register ?ap.
The fix here is to move the temporary variables into the asm macros. We
use a 32-bit __gu_tmp for 32-bit and smaller macro and a 64-bit tmp in
the 64-bit macro. The cast in the 64-bit macro has a trick of casting
through __typeof__((x)-(x)) which avoids the below warning. This was
barrowed from riscv.
arch/openrisc/include/asm/uaccess.h:240:8: warning: cast to pointer from integer of different size
I tested this in a small unit test to check reading between 64-bit and
32-bit pointers to 64-bit and 32-bit values in all combinations. Also I
ran make C=1 to confirm no new sparse warnings came up. It all looks
clean to me.

Merge commit 26d05b368a ("Merge branch 'kvm-async-pf-int' into HEAD")
tried to adapt the new interrupt based async PF mechanism to the newly
introduced IDTENTRY magic but unfortunately it missed the fact that
DEFINE_IDTENTRY_SYSVEC() doesn't call ack_APIC_irq() on its own and
all DEFINE_IDTENTRY_SYSVEC() users have to call it manually.
As the result all multi-CPU KVM guest hang on boot when
KVM_FEATURE_ASYNC_PF_INT is present. The breakage went unnoticed because no
KVM userspace (e.g. QEMU) currently set it (and thus async PF mechanism
is currently disabled) but we're about to change that.

svm->next_rip is reset in svm_vcpu_run() only after calling
svm_exit_handlers_fastpath(), which will cause SVM's
skip_emulated_instruction() to write a stale RIP.
We can move svm_exit_handlers_fastpath towards the end of
svm_vcpu_run(). To align VMX with SVM, keep svm_complete_interrupts()
close as well.

There's some driver specific fixes here plus one core fix for memory
leaks that could be triggered by a potential race condition when
cleaning up after we have split transfers to fit into what the
controller can support.

The biggest set of fixes here is those from Michał Mirosław fixing some
locking issues with coupled regulators that are triggered in cases where
a coupled regulator is used by a device involved in fs_reclaim like eMMC
storage. These are relatively serious for the affected systems, though
the circumstances where they trigger are very rare.
