Hello Jesse,

Thanks a lot for the patch. Only one of our users tested it so far
but he's using radeon, not intel. The patch didn't help him. His
server isn't even starting anymore (while it was just slow before).
He still misses a WC MTRR.

His reply and log are available at
while his original bug report (against radeonhd and radeon drivers)
Note that latest drm modules bring his WC MTRR back and solve the
original slowness problem...
