#     powerpc/rtas: rename RTAS_RMOBUF_MAX to RTAS_USER_REGION_SIZE
#     
#     RTAS_RMOBUF_MAX doesn't actually describe a "maximum" value in any
#     sense. It represents the size of an area of memory set aside for user
#     space to use as work areas for certain RTAS calls.
#     
#     Rename it to RTAS_USER_REGION_SIZE.
