While the exynos DRM support in principle can work on
multiplatform, the FIMD and IPP sections of it both
include the plat/map-base.h header file, which is
not available on multiplatform. Rather than disabling
the entire driver, we can just conditionally build
these two parts.
Without this patch, building allyesconfig results in:

Patch 9eb3e9e6f3 "drm/exynos: add support for ARCH_MULTIPLATFORM"
allowed building the exynos hdmi driver on non-samsung platforms,
which unfortunately broke compilation in combination with 22c4f42897
"drm: exynos: hdmi: add support for exynos5 hdmi", which added
an inclusion of the samsung-specific plat/gpio-cfg.h header file.
Fortunately, that header file is not required any more here, so
we can simply revert the inclusion in order to build the ARM
allyesconfig again without getting this error:

This patch considers DMA_NONE flag for other drivers not using
dma mapping framework with iommu such as 3d gpu driver or others.
For example, there might be 3d gpu driver that has its own iommu
hw unit and iommu table mapping mechnism. So in this case,
the dmabuf buffer imported into this driver needs just only
sg table to map the buffer with its own iommu table itself.
So this patch makes dma_buf_map_attachment ignore dma_map_sg call
and just return sg table containing pages if dma_data_direction
is DMA_NONE.

If one (but not both) allocations of p->chunks[].kpage[]
in radeon_cs_parser_init fail, the error path will free
the successfully allocated page, but leave a stale pointer
value in the kpage[] field. This will later cause a
double-free when radeon_cs_parser_fini is called.
This patch fixes the issue by forcing both pointers to NULL
after kfree in the error path.
The circumstances under which the problem happens are very
rare. The card must be AGP and the system must run out of
kmalloc area just at the right time so that one allocation
succeeds, while the other fails.

drm/i915: Never read FORCEWAKE
and started using something from the same cacheline instead. On the
bug reporter's machine this broke entering rc6 states after a
suspend/resume cycle. It turns out reading ECOBUS as posting read
worked fine, while GTFIFODBG did not, preventing RC6 states after
suspend/resume per the bug report referenced below. It's not entirely
clear why, but clearly GTFIFODBG was nowhere near the same cacheline
or address range as FORCEWAKE.
Trying out various registers for posting reads showed that all tested
registers for which NEEDS_FORCE_WAKE() (in i915_drv.c) returns true
work. Conversely, most (but not quite all) registers for which
NEEDS_FORCE_WAKE() returns false do not work. Details in the referenced
bug.
Based on the above, add posting reads on ECOBUS where GTFIFODBG was
previously relied on.
In true cargo cult spirit, add posting reads for FORCEWAKE_VLV writes as
well, but instead of ECOBUS, use FORCEWAKE_ACK_VLV which is in the same
address range as FORCEWAKE_VLV.
v2: Add more details to the commit message. No functional changes.

In the slow path, we are forced to copy the relocations prior to
acquiring the struct mutex in order to handle pagefaults. We forgo
copying the new offsets back into the relocation entries in order to
prevent a recursive locking bug should we trigger a pagefault whilst
holding the mutex for the reservations of the execbuffer. Therefore, we
need to reset the presumed_offsets just in case the objects are rebound
back into their old locations after relocating for this exexbuffer - if
that were to happen we would assume the relocations were valid and leave
the actual pointers to the kernels dangling, instant hang.

udldrmfb only reads the main EDID block, and if that advertises extensions

Although it may be possible to read more EDID info with the udl we simpy don't
know how, and even if trial and error gets it working on one device, that is
no guarantee it will work on other revisions. So this patch does a simple fix
in the form of patching the EDID info to report 0 extension blocks, this

"drm/nouveau/fb: merge fb/vram and port to subdev interfaces"
nv50_fb_vram_{new,del} functions were changed to use

nvc0_fb_vram_new still uses the nouveau_mm->mutex, but nvc0 doesn't
have its own fb_vram_del function, using nv50_fb_vram_del instead.
Because of this, on nvc0 a different mutex ends up being used to protect
additions and deletions to the same list.

nv50_crtc_set_clock was only called to change VPLLs, so it didn't
limit what it was used for in any way. Since nvc0_clock_pll_set is
used for all PLLs, it has to specify which PLLs the code is used for,
and only listed the first two VPLLs.

This fix was put in place to fix a bug where the eDP panel on certain
laptops fails to respond over the aux channel after suspend.
It appears that on some systems (Dell M6600, with LVDS panel) there's a
very bad interaction with the eDP init table that causes the SOR to get
very confused and not drive the panel correctly, leading to bleed.
A DPMS off/on cycle is enough to bring it back, but, this will avoid the
problem by not touching the panel GPIOs at times we're not meant to.
