I pushed them out to drm-intel-staging for wider testing. I'm not sure
that this last past merits being applied to the stable kernel (as this
does little to prevent root from breaking his machine anyway and so will
probably just suggest applying to -next instead) but the earlier patches
lead up to the important bug fixes where we were not holding the required
mutex.
Thanks,
