Merge tag 'v3.4-rc6' into drm-intel-next

Conflicts:
	drivers/gpu/drm/i915/intel_display.c

Ok, this is a fun story of git totally messing things up. There
/shouldn't/ be any conflict in here, because the fixes in -rc6 do only
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:

$ git diff 14415745b2..1fa611065

is a nice mess in intel_display.c, and the diff leaks into totally
unrelated functions, whereas

$git diff --minimal  14415745b2..1fa611065

is exactly what we want.

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).
