The final parameter to ttm_bo_reserve() is a pointer, therefore callers
should use NULL instead of 0.
Fixes a bunch of sparse warnings of this type:
warning: Using plain integer as NULL pointer

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.

This is ported from the userspace driver.
Untested on any ast2400 hw so far.

This syncs up the mode code from the X.org driver upstream,
and adds the mode validation step for hw that doesn't have
widescreen.
v2: (from Egbert Eich <eich@suse.de)
squash drm/ast: Use correct structure member for mode validation
to avoid bisect regression.
In struct drm_display_mode crtc_hdisplay and crtc_vdisplay are holding
the crtc parameters after mode fixup. For validation we need hdisplay and
vdisplay.

All drivers embed gem-objects into their own buffer objects. There is no
reason to keep drm_gem_object_alloc(), gem->driver_private and
->gem_init_object() anymore.
New drivers are highly encouraged to do the same. There is no benefit in
allocating gem-objects separately.

When porting from UMS I mistyped this from the wrong place, AST noticed
and pointed it out, so we should fix it to be like the X.org driver.

All the gem based kms drivers really want the same function to
destroy a dumb framebuffer backing storage object.
So give it to them and roll it out in all drivers.
This still leaves the option open for kms drivers which don't use GEM
for backing storage, but it does decently simplify matters for gem
drivers.

Port over the mgag200 fix to ast as it suffers the same issue.
On F19 testing, it was noticed we get a lot of errors in dmesg
about being unable to reserve the buffer when plymouth starts,
this is due to the buffer being in the process of migrating,
so it makes sense we can't reserve it.
In order to deal with it, this adds delayed updates for the dirty
updates, when the bo is unreservable, in the normal console case
this shouldn't ever happen, its just when plymouth or X is
pushing the console bo to system memory.

First convert ->cursor_set to only take the crtc lock, since that
seems to be the function with the least amount of state - the core
ioctl function doesn't check anything which can change at runtime, so
we don't have any object lifetime issues to contend.
The only thing which is important is that the driver's implementation
doesn't touch any state outside of that single crtc which is not yet
properly protected by other locking:
- ast: access the global ast->cache_kmap. Luckily we only have on crtc
on this driver, so this is fine. Add a comment.
- gma500: calls gma_power_begin|and and psb_gtt_pin|unpin, both which
have their own locking to protect their state. Everything else is
crtc-local.
- i915: touches a bit of global gem state, all protected by the One
Lock to Rule Them All (dev->struct_mutex).
- nouveau: Pre-nv50 is all nice, nv50+ uses the evo channels to queue
up all display changes. And some of these channels are device
global. But this is fine now since the previous patch introduced an
evo channel mutex.
- radeon: Uses some indirect register access for cursor updates, but
with the previous patches to protect these indirect 2-register
access patterns with a spinlock, this should be fine now, too.
- vmwgfx: I have no idea how that works - update_cursor_position
doesn't take any per-crtc argument and I haven't figured out any
other place where this could be set in some form of a side-channel.
But vmwgfx definitely has more than one crtc (or at least can
register more than one), so I have no idea how this is supposed to
not fail with the current code already. Hence take the easy way out
and simply acquire all locks (which requires dropping the crtc lock
the core acquired for us). That way it's not worse off for
consistency than the old code.

Pull drm merge (part 1) from Dave Airlie:
"So first of all my tree and uapi stuff has a conflict mess, its my
fault as the nouveau stuff didn't hit -next as were trying to rebase
regressions out of it before we merged.
Highlights:
- SH mobile modesetting driver and associated helpers
- some DRM core documentation
- i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
combined pte writing, ilk rc6 support,
- nouveau: major driver rework into a hw core driver, makes features
like SLI a lot saner to implement,
- psb: add eDP/DP support for Cedarview
- radeon: 2 layer page tables, async VM pte updates, better PLL
selection for > 2 screens, better ACPI interactions
The rest is general grab bag of fixes.
So why part 1? well I have the exynos pull req which came in a bit
late but was waiting for me to do something they shouldn't have and it
looks fairly safe, and David Howells has some more header cleanups
he'd like me to pull, that seem like a good idea, but I'd like to get
this merge out of the way so -next dosen't get blocked."
Tons of conflicts mostly due to silly include line changes, but mostly
mindless. A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

This is the initial driver for the Aspeed Technologies chips found in
servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
doesn't support the AST11xx due to lack of hw to test it on, and them requiring
different codepaths.
This driver is intended to be used with xf86-video-modesetting in userspace.
This driver has a slightly different design than other KMS drivers, but
future server chips will probably share similiar setup. As these GPUs commonly
have low video RAM, it doesn't make sense to put the kms console in VRAM
always. This driver places the kms console into system RAM, and does dirty
updates to a copy in video RAM. When userspace sets a new scanout buffer,
it forcefully evicts the video RAM console, and X can create a framebuffer
that can use all of of video RAM.
This driver uses TTM but in a very simple fashion to control the eviction
to system RAM of the console, and multiple servers.
v2: add s/r support, fix Kconfig.
