This tree includes the fixed versions of the 43 patches I sent out for
review a few weeks ago, plus an updated Kconfig options so the parts
that won't build can't build can't be selected making allyesconfig and
allnoconfig safe.

The discussion of this work was covered in lwn at:

There are a bunch more trivial patches to go that still need to be
reviewed but the core has been reviewed and tested left/right up/down
and sideways and it looks like all of the bugs have fallen out.
