[PATCH 00/33] vmwgfx device update

[Thomas Hellstrom]

The upcoming vmware svga2 hardware version 11 will introduce the concept
of "guest backed objects" or -resources. The device will in principle get all
of its memory from the guest, which has big advantages from the device
point of view.

This means that vmwgfx contexts, shaders and surfaces need to be backed
by guest memory in the form of buffer objects called MOBs, presumably
short for MemoryOBjects, which are bound to the device in a special way.

This patch series introduces guest backed object support. Some new IOCTLs
are added to allocate these new guest backed object, and to optionally provide
them with a backing MOB.

There is an update to the gallium driver that comes with this update, and
it will be pushed in the near timeframe presumably to a separate mesa branch
before merged to master.

All but the last patch have been reviewed internally. Please let me know
whether there are any concerns before i generate a pull request.

Thanks,
Thomas
