drm: block userspace under allocating buffer and having drivers overwrite it (v2)
With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory.
This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation.
Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau.

drm/nouveau: fix race condition when under memory pressure
When VRAM is running out it's possible that the client's push buffers get
evicted to main memory. When they're validated back in, the GPU may
be used for the copy back to VRAM, but the existing synchronisation code
only deals with inter-channel sync, not sync between PFIFO and PGRAPH on
the same channel. This leads to PFIFO fetching from command buffers that
haven't quite been copied by PGRAPH yet.
This patch marks push buffers as so, and forces any GPU-assisted buffer
moves to be done on a different channel, which triggers the correct
synchronisation to happen before we submit them.

entirely serialised by drm_global_mutex and so can be dropped. The

drm: Fix support for PCI domains
(For some reason I thought that went in ages ago ...)
This fixes support for PCI domains in what should hopefully be a backward
compatible way along with a change to libdrm.
When the interface version is set to 1.4, we assume userspace understands
domains and the world is at peace. We thus pass proper domain numbers
instead of 0 to userspace.
The newer libdrm will then try 1.4 first, and fallback to 1.1, along with
ignoring domains in the later case (well, except on alpha of course)
