Here's an update that makes all the code generic.  Jakob suggested that
we do the mode_set_base call out of the caller's context so we don't
block the caller waiting for the GTT domain transition (effectively
waiting until rendering finishes).  I definitely want to do this, but
I'll have to add a way to communicate the necessary flip data from the
ioctl to the new work function.
