I've updated the repo of patches to have rt3 and rt4 on master branch.

In my fixes branch (now v3.6.2-rt4-fixes) there is only the cosmetic fix
of adding a subject to the power-use-generic-rwsem-on-rt.patch,
everything else is in the main tarballs.

There is a gregkh v3.6.3 release - the series applies onto that with
only a trivial patch refresh required to kgb-serial-hackaround.patch

In fact, quilt may not even bother to warn about it, but git-am will
stop and ask you to double check things.  If git-am still fails when
we get to v3.6.3-rt5, then I'll refresh it on the -fixes branch.
