drm/i915/hsw: Set correct Haswell PTE encodings)
actually seems to prefer the default PTE encoding as age 3. Presumably,
this is in part due to the use of MOCS to override the PTE encodings
when appropriate.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes
two outstanding exynos fixes

This patch resolves a dead lock issue that could be incurred when
exynos_drm_crtc_dpms function was called.
The exynos_drm_crtc_dpms function waits for the completion of pended
page flip events. However, preclose callback - this releases all unhandled
page flip events - is called prior to the exynos_drm_crtc_dpms function call
when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms
to wait infiniately for the completion of the page flip events.
This patch releases the unhandled page flip events at postclose instead
of preclose so that exynos_drm_crtc_dpms function can be waked up.
Changelog v2:
- fix a memory leak when drm is closed.
. it has a memory leak when a requeste page flip is handled after
drm_events_release() is called and before drm_fb_release()
is called. At this time, a drm_pending_event will not be freed.
So also this chage releases the drm_pending_event at postclose().
And it calls drm_vblank_put() for pair if there is any unhandled page
flip event.

Previously the association to a DC was done via the encoder's .crtc
field. That has the disadvantage that when an encoder is detached from
its CRTC, that field is set to NULL, leading to situations where it is
impossible to access the DC registers required by the RGB output.
However, the coupling between DC and RGB output is really fixed on
Tegra. While they can be detached logically in DRM, the RGB output can
rely on the DC's existence.

Also request kernel ttm_buffer objects for buffer objects that obviously
aren't visible to user-space, and save some device address space.
The accounting was broken in a couple of ways:
1) We did not differentiate between user dma buffers and kernel dma buffers.
2) The ttm_bo_acc_size function is broken in that it
a) Doesn't take into account the size of the optional dma address array,
b) Doesn't take into account the fact that drivers typically embed the
ttm_tt structure.
This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific
function to do the job.

Addresses
"[BUG] completely bonkers use of set_need_resched + VM_FAULT_NOPAGE".
In the first occurence it was used to try to be nice while releasing the
mmap_sem and retrying the fault to work around a locking inversion.
The second occurence was never used.
There has been some discussion whether we should change the locking order to
mmap_sem -> bo_reserve. This patch doesn't address that issue, and leaves
that locking order undefined. The solution that we release the mmap_sem if
tryreserve fails and wait for the buffer to become unreserved is something
we want in any case, and follows how the core vm system waits for pages
to be come unlocked while releasing the mmap_sem.
The code also outlines what needs to be changed if we want to establish the
locking order as mmap_sem -> bo::reserve.
One slight issue that remains with this code is that the fault handler might
be prone to starvation if another thread countinously reserves the buffer.
IMO that usage pattern is highly unlikely.

If ttm_bo_move_memcpy was instructed to move a non-populated ttm to
io memory, it would first populate the ttm, then move the data and then
destroy the ttm. That's stupid. However, some drivers might have relied on
this to clear io memory from old stuff. So instead of a NOP, which would
be the most efficient, just clear the destination.

A lockdep warning is hit when evicting surfaces and reserving the backup
buffer. Since this buffer can only be reserved by the process holding the
surface reservation or by the buffer eviction processes that use tryreserve,
there is no real deadlock here, but there's no other way to silence lockdep
than to use a tryreserve. This means the reservation might fail if the buffer
is about to be evicted or swapped out, but we now have code in place to
handle that reasonably well.

If no reservation ticket is given to the execbuf reservation utilities,
try reservation with non-blocking semantics.
This is intended for eviction paths that use the execbuf reservation
utilities for convenience rather than for deadlock avoidance.

git://people.freedesktop.org/~danvet/drm-intel into drm-fixes
Just a small pile of fixes for bugs and a few regressions. I'm still
trying to track down a driver load hang on my g33 (which infuriatingly
doesn't happen when loading the module manually after boot), somehow
bisecting loves to go astray on this one :( And there's a (harmless)
locking WARN in the suspend code due to one of Jesse's vlv backlight
rework patches. Otherwise nothing outstanding afaik.
* tag 'drm-intel-fixes-2013-11-20' of git://people.freedesktop.org/~danvet/drm-intel:
drm/i915: Fix gen3 self-refresh watermarks
drm/i915: Replicate BIOS eDP bpp clamping hack for hsw
drm/i915: Do not enable package C8 on unsupported hardware
drm/i915: Hold pc8 lock around toggling pc8.gpu_idle
drm/i915: encoder->get_config is no longer optional

drm/i915: restore the early forcewake cleanup
Partially revert "drm/i915: tune the RC6 threshold for stability"
drm/i915: flush cursors harder
i915: Use 120MHz LVDS SSC clock for gen5/gen6/gen7
x86/early quirk: use gen6 stolen detection for VLV

drm/i915: Use adjusted_mode appropriately when computing watermarks
I guess we should renable the enabled local variable into something a
notch more descriptive, but that's something for -next.
The effect on my i945gme netbook is pretty severe amounts of underruns
- usually the very first pixel gets used for the entire screeen.

we've forgotten to replicate this hack. So let's do it that.
Note for backporters: The above commit and all it's depencies need to

If the hardware does not support package C8, then do not even schedule
work to enable it. Thereby we can eliminate a bunch of dangerous work.

We must have one to fill out the adjusted_mode.crtc_clock. And with
the tv encoder fixed up every encoder we have has a ->get_config
callback. So we can drop the checks.

We need this to properly fill in adjusted_mode.crtc_clock, otherwise
the state checker gets unhappy. This seems to have been forgotten in
the big clock rework in
