2e3cc8cff6 drm/vmwgfx: Fix compiler warning with 32-bit dma_addr_t
When the size of dma_addr_t was 32 bits, the compiler warned
about the size of the 32 bit shift being larger than the size
of the data type.

Reported by Intel's kbuild robot.

b9eb1a6174 drm/vmwgfx: Kill a bunch of sparse warnings
We're giving up all attempts to keep cpu- and device byte ordering separate.

This silences sparse when compiled using
make C=2 CF="-D__CHECK_ENDIAN__"

9b590783b3 drm/vmwgfx: Avoid cmdbuf alloc sleeping if !TASK_RUNNING
If the command buffer pool is out of space, the code waits until space is
available. However since the condition code tries to allocate a range manager
node while !TASK_RUNNING we get a kernel warning.

Avoid this by pre-allocating the mm node. This will also probably be more
efficient.

3eab3d9eef drm/vmwgfx: Add command buffer support v3
Add command buffer support.
Currently we don't implement preemption or fancy error handling.
Tested with a couple of mesa-demos, compiz/unity and viewperf maya-03.

v2:
- Synchronize with pending work at command buffer manager takedown.
- Add an interface to flush the current command buffer for latency-critical
  command batches and apply it to framebuffer dirtying.

v3:
- Minor fixes of definitions and typos to address reviews.
- Removed new or moved branch predictor hints.
