[Intel-xe] [PATCH 0/3] Minor batchbuffer handling fixes

Xe's internal batchbuffer code is not properly considering the hardware
prefetch requirements.  It is also emitting duplicate
MI_BATCH_BUFFER_END instructions in the workaround batchbuffer.

Matt Roper (3):
  drm/xe: Include hardware prefetch buffer in batchbuffer allocations
  drm/xe: Adjust batchbuffer space warning when creating a job
  drm/xe: Don't emit extra MI_BATCH_BUFFER_END in WA batchbuffer
