Linux never used to do this...until a month:

       agp/intel: Serialise after GTT updates
Include &lt;sys/atomic.h&gt; for membar_producer.
(Why didn't this fail in my build?)
Pass cache-related flags through to the GTT on pre-SNB devices.
I had assumed for ages this would increase the amount of caching and
thereby increase the chance of stale caches leading to rendering
glitches.  But apparently I was wrong, and failing to pass these
through was causing all sorts of problems!
Dedup the NetBSD portion of the code (ok Riastradh), no functional change.
Don't return events that are too large and leave them in the list.
Apply access control to gem mmap.
fix gcc is stupid.
