Subject: [PATCH] drm/i915: fix hibernation since 4bdadb9785696439c6e2b3efe34aa76df1149c83

From: Linus Torvalds <torvalds@...ux-foundation.org>

Since 4bdadb9785696439c6e2b3efe34aa76df1149c83, we've been passing
GFP_MOVABLE where we weren't before caused hibernate on Intel hardware
to results in a lot of memory corruptions on resume.
