The following git pull request adds the Xenbus infrastructure for Xen
backend drivers to the upstream 2.6.37-rc kernel. It essentially
refactors the frontend xenbus scaffolding into frontend and common and
then adds the backend part.
All but one patch is cherry-picked from xen.git xen/dom0/backend/core.
It wasn''t possible to simply merge the branch because that pulled in a
bunch of 2.6.32-style dom0 support which conflicts with what is now
upstream.
The only cherry-picked patch which required changes was the "xen:
separate out frontend xenbus" commit which needed updating because the
code which it moves has changed since it was written (primarily the
changes to wait_for_devices e.g. c6e1971139be, f8dc33088feb,
ae7888012969).
The last patch is new and fixes up the checkpatch issues in the
aggregate of the previous commits. I did it this way rather than fixing
individual patches since I wanted to retain the history as is.
I have a WIP set of changes which port netback onto this infrastructure
(the port works but still uses PageForeign and hence is not
upstreamable). I also tested with a merge of
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git
devel/xen-pciback-0.1 and the result seemed functional.
