Newer asics don't have specific UVD states.
Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

Newer asics have a lot of vram so it's less of an
issue to waste a little more space for the gart
page table.  This gives us some additional gart space
before having to migrate to non-gart system ram
for games, etc. where we use up most of vram.

1. Handle the the thermal state directly in the work handler.
Remove the state selection function since nothing else uses it now.
2. On some asics there is no thermal state, so we just use a regular
state and force the low performance state.

Use the UVD handle information to determine which

late in the -rc cycle, but Linus was making noises about not getting real
fixes which are cc: stable. So here we go ;-)

  drm/i915: ivb: fix edp voltage swing reg val

Fix the typo introduced in

commit 1a2eb460
Author: Keith Packard <keithp@keithp.com>
Date:   Wed Nov 16 16:26:07 2011 -0800

    drm/i915: Hook up Ivybridge eDP

This fixes eDP link-training failures and cases where all voltage swing
/pre-emphasis levels were tried and failed during clock recovery and -
as a fallback - we go on to do channel equalization with the last voltage
swing/pre-emphasis level which will succeed. Both issues can lead to a
blank screen.

v2:
- improve commit message

    // Input buffer (default 4 byte aigned)

    // actual search start (to mimick 2 byte alignment)

This should actually be returning an ERR_PTR on error instead of NULL.
That was how it was designed and all the callers expect it.

[AV: actually, that's what "VFS: Make clone_mnt()/copy_tree()/collect_mounts()
return errors" missed - originally collect_mounts() was expected to return
NULL on failure]
