3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Anholt <e...@anholt.net>

commit fc74d8e01165b567922921d110b6d16320a61fa6 upstream.

Older specs claimed this was bit 11, but newer specs and the actual
simulator code say it was bit 12.  Regardless, we don't use MI_FLUSH,
or try to enable it any more.
