Merge tag 'v4.0-rc6' into drm-intel-next

Backmerge Linux 4.0-rc6 because conflicts are (again) getting out of
hand. To make sure we don't lose any bugfixes from the 4.0-rc5-rc6
flurry of patches we've applied them all to -next too.

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

Always take the version from -next, we've already handled all
conflicts with explicit cherrypicking.
