Now that drm core knows about private planes, it cleans them up for us.
Trying to do this twice results in badness.

To ease debugging, add debugfs file which can be cat/tail'd to log
submits, along with fence #. If GPU hangs, you can look at 'gpu'
debugfs file to find last completed fence and current register state,
and compare with logged rd file to narrow down the DRAW_INDX which
triggered the GPU hang.

The hotplug detect and irq does not seem to be reliable on all devices
for some reason. For now it is more reliable to use polling, and give
preference to raw gpio status if it disagrees with the debounced hpd
status.

shmem_read_mapping_page() uses mapping_gfp_mask(mapping) as default gfp
mask. No reason to use shmem_read_mapping_page_gfp() directly if we want
the default behavior.

shmem: replace page if mapping excludes its zone
The gem-comment about wrongly placed DMA32 pages is no longer valid.
Replace it with a proper comment but keep the BUG_ON() to verify correct
shmem behavior.

The shmobile DRM driver is only useful on SuperH and shmobile unless
build testing. I am dropping the SuperH dependencies though because
the driver doesn't even build there, so in practice it is an arm-only
driver for now.

The 800x600 (SVGA) screen resolution was lacking in the set of
built-in selectable EDID screen resolutions that can be used to
repair misbehaving monitor firmware.
This patch adds the related data set and expands the documentation.
Note that the SVGA bit occupies a different byte to all the existing
users of the established timing bits forcing a rework of the
ESTABLISHED_TIMINGS_BITS macro.
Tested new EDID on an aged (and misbehaving) industrial LCD panel;
existing EDIDs still pass edid-decode's checksum checks.

Pull in latest updates to AST driver.
* 'ast-updates' of ssh://people.freedesktop.org/~/linux:
drm/ast: initial DP501 support (v0.2)
drm/ast: rename the mindwm/moutdwm and deinline them
drm/ast: resync the dram post code with upstream
drm/ast: add AST 2400 support.
drm/ast: add widescreen + rb modes from X.org driver (v2)
This is the initial attempt at porting the DP501 code from the userspace
driver,
the firmware file is in
http://people.freedesktop.org/~airlied/ast_dp501_fw.bin
this should really be exposed as another encoder/connector that is cloneable
v0.2:
init 3rd tx properly,
add scratch reduction of VRAM size
backup firmware properly.
