This is a note to let you know that I have just added a patch titled
drm/i915: Remove BUG_ON from i915_gem_evict_something
to the drm-next branch of the 2.6.32+drm33-longterm tree which can be found at
http://git.kernel.org/?p=linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git;a=shortlog;h=refs/heads/drm-next
If you, or anyone else, feels it should not be added to the drm33-longterm tree,
please reply to this email not later than 8 days after this email was sent.
Thanks.

Subject: [PATCH] drm/i915: Remove BUG_ON from i915_gem_evict_something
BugLink: https://bugs.launcpad.net/bugs/828550
According to Chris Wilson this BUG_ON was just paranoia and never
something the kernel should explode on. He later removed it in
upstream commit e39a01501b228e1be2037d5bddccae2a820af902. So let's
just remove it.
