Hey Aravind,
Just a couple quick comments (inline below).. overall patchset looks
to be in reasonably good shape. It would be nice if you could resend
and CC dri-devel@xxxxxxxxxxxxxxxxxxxxx.. and format-patch as a
patchset (so subject lines have the "[PATCH x/y]" since things don't
always show up in the inbox in FIFO order). I'll have a closer look
and may have a minor nit-pick or two, but the overall structure of
things in the patchset looks good.

you'll need a ~0 sentinel at the end of that.. which was something I
