Cursors need to be in the GTT domain when being accessed by the GPU.
Previously this was a fortuitous byproduct of userspace using pwrite()
to upload the image data into the cursor. The redundant clflush was
removed in commit 9b8c4a and so the image was no longer being flushed
out of the caches into main memory. One could also devise a scenario
where the cursor was rendered by the GPU, prior to being attached as the
cursor, resulting in similar corruption due to the missing MI_FLUSH.
Fixes:
Bug 28335 - Cursor corruption caused by commit 9b8c4a0b21

The host may change the layout and, since the change is
communicated to the master, the master needs a way to
communicate the change to the kernel driver.
The minor version number is bumped to advertize the
availability of this feature.

Sandybridge(Gen6) has new format for PIPE_CONTROL command,
the flush and post-op control are in dword 1 now. This
changes command length field for difference between Ironlake

I tried to test this with noop request and issue PIPE_CONTROL

seems work fine. Hopefully we don't need workaround like on

We can avoid an early clflush when pwriting if we use the current CPU
write domain rather than moving the object to the GTT domain for the
purposes of the pwrite. This has the advantage of not flushing the
presumably hot data that we want to upload into the bo, and of ascribing
the clflush to the execution when profiling.

This particular warning is harmless as we emit during the normal
pinning process where the batch buffer requires more fences than is
available without eviction. Only if we fail to evict enough fences does
this become a problem, so include the requested number of fences in the
ultimate *error* message.
v2: Remember to compile test even trial patches to remove warnings.
