Subject: [PATCH 3.9-stable]  drm.h: Fix DRM compilation with bare-metal
 toolchain.'Mark Brown'

This patch looks like it should be in the 3.9-stable tree, should we apply
it?

------------------

From: "Paul Sokolovsky <paul.sokolovsky@...aro.org>"

commit b6330548383cf18d608faf1c2dc0c81c60476233 upstream

An ifdef in drm.h expects to be compiled with full-fledged Linux
toolchain, but it's common to compile kernel with just bare-metal
toolchain which doesn't define __linux__. So, also add __KERNEL__
check.

[nm@...com: port forward to 3.9-rc6 and post to dri devel for feedback as
RFC]
