drm/radeon: make use of radeon_gem_init() consistent
All radeon_gem_init() does is initialize the gem objects
list. radeon_device.c does this explicitly. r600+ calls
radeon_gem_init() so the list gets initialized twice. Older
asics don't call it at all and rely on the the init in
radeon_device.c. Just call radeon_gem_init() in radeon_device.c
and remove the explicit calls from all the newer asics.
All asics call radeon_gem_fini() in their fini pathes. That
could possibly be cleaned up too.

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.

drm: pass dev to drm_vm_{open,close}_locked()
Previously these functions would assume that vma->vm_file was the
drm_file. Although if in some cases if the drm driver needs to use
something else for the backing file (such as the tmpfs filp) then this
assumption is no longer true. But vma->vm_private_data is still the
GEM object.
With this change, now the drm_device comes from the GEM object rather
than the drm_file so the driver is more free to play with vma->vm_file.
The scenario where this comes up is for mmap'ing of cached dmabuf's
for non-coherent systems, where the driver needs to use fault handling
and PTE shootdown to simulate coherency. We can't use the vma->vm_file
of the dmabuf, which is using anon_inode's address_space. The most
straightforward thing to do is to use the GEM object's obj->filp for
vma->vm_file in all cases, for which we need this patch.

We store the last allocated bo in last, we always try to allocate

the first one that should no longer be in use by the GPU.
If it's not the case we skip over the bo after last to the closest

block we report failure to allocate.

touch functions that have not been changed in -next.
The offending commits in drm-next are 14415745b2..1fa611065 which
simply move a few functions from intel_display.c to intel_pm.c. The
problem seems to be that git diff gets completely confused:
Unfortunately there seems to be no way to teach similar smarts to the
merge diff and conflict generation code, because with the minimal diff
there really shouldn't be any conflicts. For added hilarity, every
time something in that area changes the + and - lines in the diff move
around like crazy, again resulting in new conflicts. So I fear this
mess will stay with us for a little longer (and might result in
another backmerge down the road).

Btrfs: avoid sleeping in verify_parent_transid while atomic
verify_parent_transid needs to lock the extent range to make
sure no IO is underway, and so it can safely clear the
uptodate bits if our checks fail.
But, a few callers are using it with spinlocks held. Most
of the time, the generation numbers are going to match, and
we don't want to switch to a blocking lock just for the error
case. This adds an atomic flag to verify_parent_transid,
and changes it to return EAGAIN if it needs to block to
properly verifiy things.

TTY: pdc_cons, fix regression in close
The test in pdc_console_tty_close '!tty->count' was always wrong
because tty->count is decremented after tty->ops->close is called and
thus can never be zero. Hence the 'then' branch was never executed and
the timer never deleted.
This did not matter until commit 5dd5bc40f3b6 ("TTY: pdc_cons, use
tty_port"). There we needed to set TTY in tty_port to NULL, but this
never happened due to the bug above.
So change the test to really trigger at the last close by changing the
condition to 'tty->count == 1'.
Well, the driver should not touch tty->count at all. It should use
tty_port->count and count open count there itself.

drm/i915: remove modeset reset from i915_reset
On gen4+ we don't reset the display unit, so resetting the complete
modeset state should not be necessary.
We can't do reset on gen3 anyway, which leaves us with gen2 reset:
According to Chris Wilson, that doesn't work so great, so he suggested
we just ignore that. If the need ever arrises, we can re-add it later
on.

drm/i915: allow the existing error_state to be destroyed
... by writing (anything) to i915_error_state.
This way we can simulate a bunch of gpu hangs and run the error_state
capture code every time (without the need to reload the module).
To make that happen we need to abandon the simple seq_file wrappers
provided by the drm core. While at it put the new error_state
refcounting to some good use and associated the error_state to the
debugfs when opening the file. Otherwise the error_state could change
while someone is reading it. This should help greatly when we finally
get around to split up the giant single seq_file block that the
error_state file currently is into smaller parts.

drm/i915: add interface to simulate gpu hangs
gpu reset is a very important piece of our infrastructure.
Unfortunately we only really it test by actually hanging the gpu,
which often has bad side-effects for the entire system. And the gpu
hang handling code is one of the rather complicated pieces of code we
have, consisting of
- hang detection
- error capture
- actual gpu reset
- reset of all the gem bookkeeping
- reinitialition of the entire gpu
This patch adds a debugfs to selectively stopping rings by ceasing to
update the hw tail pointer, which will result in the gpu no longer
updating it's head pointer and eventually to the hangcheck firing.
This way we can exercise the gpu hang code under controlled conditions
without a dying gpu taking down the entire systems.
Patch motivated by me forgetting to properly reinitialize ppgtt after
a gpu reset.
Usage:
echo $((1 << $ringnum)) > i915_ring_stop # stops one ring
echo 0xffffffff > i915_ring_stop # stops all, future-proof version
then run whatever testload is desired. i915_ring_stop automatically
resets after a gpu hang is detected to avoid hanging the gpu to fast
and declaring it wedged.
v2: Incorporate feedback from Chris Wilson.
v3: Add the missing cleanup.
v4: Fix up inconsistent size of ring_stop_read vs _write, noticed by
Eugeni Dodonov.
