AFBC buffers include additional metadata which increases the required
allocation size. Implement the appropriate size validation and sanity
checking for AFBC buffers.
Added malidp specific function for framebuffer creation. This checks
if the framebuffer has AFBC modifiers and if so, it verifies the
necessary constraints on the size, alignment, offsets and pitch.
Changes from v2:
- Replaced DRM_ERROR() with DRM_DEBUG_KMS() in
malidp_verify_afbc_framebuffer_caps() and malidp_verify_afbc_framebuffer_size()

Add support for compressed framebuffers that are described using
the framebuffer's modifier field. Mali DP uses the rotation memory for
the decompressor of the format, so we need to check for space when
the modifiers are present.

Mali-DP650 supports warming up the SMMU translations, by sending
requsts to the SMMU before a buffer is read.
There are two modes supported:
- PARTIAL: could be enabled when the buffer is composed of 4K or 64K
pages, the display hardware will send a configurable number of
requests before the actual reading.
- FULL: could be enabled when the buffer is composed of 1M or 2M
pages, the display hardware will send requests before reading for
all pages composing the buffer.
This patch adds a mechanism for detecting the page size and set the
MMU prefetch mode if possible.
Changes since v1:
- For imported buffers use the already populated
drm_gem_cma_object.sgt instead of calling
driver.gem_prime_get_sg_table, which works just for buffers
allocated through the gem_cma API.

Checks the pixel blending mode and plane alpha value when
do the plane_check. Mali DP supports blending the current plane
with the background either based on the pixel alpha blending
mode or by using the layer's alpha value, but not both at the
same time. If both case, plane_check will return failed.
Sets the HW when doing plane_update accordingly. If plane alpha
is the 0xffff, set the pixel blending bits accordingly. If not
we'd set ALPHA bit as zero and layer alpha value.
Changes since v1:
- Introduces to use it in the malidp driver, which depends on
the plane alpha patch
Changes since v2:
- Refines the comments of drm/mali-dp patchset
Changes since v3:
- Adds hardware limitation check
Changes since v4:
- Updates on drm/malidp, hardware limitation check only when
the format has alpha pixel.
- Rebases on drm-misc-next.

When we want to writeback to memory in NV12 format we need to program
the RGB2YUV coefficients. Currently, we don't program the coefficients
and NV12 doesn't work at all.
This patchset fixes that by programming a sane default(bt709, limited
range) as rgb2yuv coefficients.
In the long run, probably we need to think of a way for userspace to
be able to program that, but for now I think this is better than not
working at all or not advertising NV12 as a supported format for
memwrite.
Changes since v1:
- Write the rgb2yuv coefficients only once, since we don't change
them at all, just write them the first time NV12 is programmed,
suggested by Brian Starkey, here [1]

Currently, if userspace calls drm_wait_vblank before the crtc is
activated the crtc vblank_enable hook is called, which in case of
malidp driver triggers some warninngs. This happens because on
device init we don't inform the drm core about the vblank state
by calling drm_crtc_vblank_on/off/reset which together with
drm_vblank_get have some magic that prevents calling drm_vblank_enable
when crtc is off.

Errata i878 says that MPU should not be used to access RAM and DMM at
the same time. As it's not possible to prevent MPU accessing RAM, we
need to access DMM via a proxy.
This patch changes DMM driver to access DMM registers via sDMA. Instead
of doing a normal readl/writel call to read/write a register, we use
sDMA to copy 4 bytes from/to the DMM registers.
This patch provides only a partial workaround for i878, as not only DMM
register reads/writes are affected, but also accesses to the DMM mapped
buffers (framebuffers, usually).

A DMM timeout "timed out waiting for done" has been observed on DRA7
devices. The timeout happens rarely, and only when the system is under
heavy load.
Debugging showed that the timeout can be made to happen much more
frequently by optimizing the DMM driver, so that there's almost no code
between writing the last DMM descriptors to RAM, and writing to DMM
register which starts the DMM transaction.
The current theory is that a wmb() does not properly ensure that the
data written to RAM is observable by all the components in the system.
This DMM timeout has caused interesting (and rare) bugs as the error
handling was not functioning properly (the error handling has been fixed
in previous commits):
* If a DMM timeout happened when a GEM buffer was being pinned for
display on the screen, a timeout error would be shown, but the driver
would continue programming DSS HW with broken buffer, leading to
SYNCLOST floods and possible crashes.
* If a DMM timeout happened when other user (say, video decoder) was
pinning a GEM buffer, a timeout would be shown but if the user
handled the error properly, no other issues followed.
* If a DMM timeout happened when a GEM buffer was being released, the
driver does not even notice the error, leading to crashes or hang
later.
This patch adds wmb() and readl() calls after the last bit is written to
RAM, which should ensure that the execution proceeds only after the data
is actually in RAM, and thus observable by DMM.
The read-back should not be needed. Further study is required to understand
if DMM is somehow special case and read-back is ok, or if DRA7's memory
barriers do not work correctly.

A reasonably big batch of fixes due to me being away for a few weeks.
A fix for the TM emulation support on Power9, which could result in
corrupting the guest r11 when running under KVM.
Two fixes to the TM code which could lead to userspace GPR corruption
if we take an SLB miss at exactly the wrong time.
Our dynamic patching code had a bug that meant we could patch freed
__init text, which could lead to corrupting userspace memory.
csum_ipv6_magic() didn't work on little endian platforms since we
optimised it recently.
A fix for an endian bug when reading a device tree property telling
us how many storage keys the machine has available.
Fix a crash seen on some configurations of PowerVM when migrating the
partition from one machine to another.
A fix for a regression in the setup of our CPU to NUMA node mapping
in KVM guests.
A fix to our selftest Makefiles to make them work since a recent
change to the shared Makefile logic."

It is possible that a failure can occur during the scheduling of a
pinned event. The initial portion of perf_event_read_local() contains
the various error checks an event should pass before it can be
considered valid. Ensure that the potential scheduling failure
of a pinned event is checked for and have a credible error.
