71ae3df244 drm: remove writeq/readq function definitions
Instead of rewriting write/readq, use linux/io-64-nonatomic-lo-hi.h which
already have them.

4cda878b12 drm: Kill DRM_SUSER
Checking directly for the right capability is simpler. Also this rids
us of a few places that use DRM_CURRENTPID.

e9f0d76f3b drm: Kill DRM_IRQ_ARGS
I've killed them a long time ago in drm/i915, let's get rid of this
remnant of shared drm core days for good.

bfd8303af0 drm: Kill DRM_HZ
We don't have any userspace interfaces that use HZ as a time unit, so
having our own DRM define is useless.

Remove this remnant from the shared drm core days.

d2e546b855 drm: rip out DRM_AGP_MEM and DRM_AGP_KERN
The <linux/agp_backend.h> header provides dummy functions and
fallbacks, so no need for screaming macros.

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.

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.
