(xen) stable/for-linus-3.3 patches for 3.3-rc0

Hey Linus,

Please git pull the following git branch:

git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-3.3

There are eight exciting patchsets in this branch:
- SysFS documentation updates. We are slowly updating them to make sure that the SysFS entires are properly documented.
- Making the grant system able to use more fancier types of grants to speed-up guest to guest exchange of data (sub-page and transitive grants).
- Updates in the backends to be able to export the Xen backends in an Hardware Virtualized Management (HVM) guest. We usually export those backends in the initial domain (dom0), but are moving slowly to make it possible to do it any guest (PV or HVM).
- Better driver to deal with memory type ioctls calls. In the past we were doing ioctls on /proc/xen/priv_cmd (yuck) and with this are moving to doing it in /dev/xen/priv_cmd.
- Fix a security issues were the guest could try to send a nasty (out of band) message and potentially cause mishap.
- Remove duplicate initialization fields in the backend drivers.
- Jeremy is now working for a fancy new startup so changing the MAINTAINERS file to reflect that his contribution are done during his private time.
- Sensible config options. We had some that weren't all that good so adjusting them properly.
- Bug-fixes.

That is it! Please push

Please, you too also start using -M (and --summary) for the diffstat output.

It should look like this:

create mode 100644 Documentation/ABI/stable/sysfs-bus-xen-backend create mode 100644 Documentation/ABI/stable/sysfs-devices-system-xen_memory rename drivers/xen/{xenfs => }/privcmd.c (92%)

which is a lot more true about the *real* changes.

This is even included in Documentation/SubmittingPatches (not that anyone reads documentation ;).
