linux-next: manual merge of the drm tree with Linus' tree

From: Stephen Rothwell
Date: Tue Feb 12 2013 - 23:49:16 EST

Hi Dave,

Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/radeon/evergreen_cs.c between commit de0babd60d8d
("drm/radeon: enforce use of radeon_get_ib_value when reading user cmd")
from Linus' tree and commit 0fcb6155cb5c ("radeon/kms: cleanup async dma
packet checking") from the drm tree.

I fixed it up (I think (I did it fairly mechanically) - see below) and
can carry the fix as necessary (no action is required - but it might be
worth doing this merge yourself before asking Linus to pull - you could
just *merge* the above commit from Linus' tree (or the head of the branch
that Linus merged)).

Cheers,
