[Lucas De Marchi]

Hi Dave and Sima,

First patch has an important impact to userspace, changing the cahcing
mode to write-back for system memory on DGFX. In this case we introduce
a limitation in the cache selection uapi that is transparent to UMDs. I
mean, no change on their side is needed.  Coherence is maintained, but
with some known possible and acceptable/accepted differences in CPU
access speed.

Second patch fixes a leak when finalizing hdcp gsc.
