drm/i915: Rename PIPE_CONTROL bit defines to be less terse.
Browse files Browse the repository at this point in the history
"STALL_AT_SCOREBOARD" is much clearer than "STALL_EN" now that there are
several different kinds of stalls.  Also, "INSTRUCTION_CACHE_INVALIDATE"
is a lot easier to understand at a glance than the terse "IS_FLUSH."
