Subject: [gem] Set write domain to CPU when doing pwrite.
X-Git-Tag: submit/1.0/20121108.012404~757^2~129
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6aeff6b9e32b61beed0d5c3d871968fa6217b79d;p=profile%2Fivi%2Flibdrm.git

[gem] Set write domain to CPU when doing pwrite.

Leave the flush call in place, which can fix domains up if necessary.
