Daniel Vetter 48764bf43f drm/i915: add i915_lp_ring_sync helper
This just waits until the hw passed the current ring position with
cmd execution. This slightly changes the existing i915_wait_request
function to make uninterruptible waiting possible - no point in
returning to userspace while mucking around with the overlay, that
piece of hw is just too fragile.

Also replace a magic 0 with the symbolic constant (and kill the then
superflous comment) while I was looking at the code.

Dave Airlie 522b5cc7ce drm: fix missing inline function on 32-bit powerpc.
The readq/writeq really need to be static inline on the arches which
don't provide them.

Dave Airlie 87f0da5535 drm: add DRM_READ/WRITE64 wrappers around readq/writeq.
The readq/writeq stuff is from Dave Miller, and he
warns users to be careful about using these. Plans are only
r600 to use it so far.

Dave Airlie c0e09200dc drm: reorganise drm tree to be more future proof.
With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.

This restructures the drm along the lines of other kernel components.

It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.
