drm-misc is a non-rebasing tree (because it's got lots of
maintainers/committers). Which means we need fixup patches now.

Not that currently drm-misc-next isn't in linux-next because of the merge
window, so just rebasing on top of linux-next wont work (at least not
until -rc1 is out). You can get the tree here meanwhile:
