Subject: drm/radeon: Restrict offset for legacy hardware cursor.
X-Git-Tag: v3.4-rc1~143^2~21
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c4353016dac10133fa5d8535af83f0c4845a2915;p=pandora-kernel.git

drm/radeon: Restrict offset for legacy hardware cursor.

The hardware only takes 27 bits for the offset, so larger offsets are
truncated, and the hardware cursor shows random bits other than the intended
ones.
