1. Document how to use SMI system management interface to receive SVM
events, define string format macro for user mode.
2. Increase the event kfifo size, so less chance to drop event.
3. Output migrate end event with error code if migration failed.
4. Report dropped event count if fifo is full.

v3:
  Simplify event drop count handling (James Zhu) 

Philip Yang (4):
  drm/amdkfd: Document and define SVM events message macro
  drm/amdkfd: Output migrate end event if migrate failed
  drm/amdkfd: Increase SMI event fifo size
  drm/amdkfd: SMI report dropped event count
