txattr() had been done in commit ce23e64. Unlike
->getxattr() (which is used by both selinux and smack instances of
->d_instantiate()) ->setxattr() is used only by smack one and unfortunately

Basically, you are right and source offset register can be used. But
because of limitation of resolution for mixer up to 1920x1080, I
considered modified soruce dma address to set one frame buffer, which is
bigger than 1920x1080, on to both fimd and hdmi.
