[RFC PATCH] drm.h: Fix DRM compilation with bare-metal toolchain.

[Nishanth Menon <nm@ti.com>]

From: Paul Sokolovsky <paul.sokolovsky@linaro.org>

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

Paul, Dri devel list,
I picked up this patch from linaro tree:
https://git.linaro.org/gitweb?p=people/asac/android/kernel/lt-ti.git;a=patch;h=719fbc876740cf75e82dd082ae5a00dfcf6fff7a
Discussion thread: http://lists.linaro.org/pipermail/linaro-dev/2011-June/thread.html#4874
Seems to me as a valid fix even for upstream perhaps?
Regards,
Nishanth Menon
