   In interest of getting reviewed patches in sonner, last two patches
   dropped for a later series.

   Place additional documentation of intel_engine_cs function
   pointers to inlined in struct.

   Fix documentation error about lazy creation of intel_ringbuffer
   and backing store in intel_lrc.c.
   (Caught by Chris Wilson)

   More documentation: emphasize that handling of batchbuffer
   requests creates a request struct that is added to the
   dependency tree and that the inform to the hardware that
   there is new data on a ringbuffer is deferred until dependencies
   are satsified.

   Break patch into more digestable chunks.  

   More documentation: intel_ringbuffer, sequence number.

   Call out GEM_EXECBUFFER as deprecated.
   Place code detailed documentation in source files.
