[Xen-devel] Backport requests for 4.1-testing.hg

["Andres Lagar-Cavilla" <andres@xxxxxxxxxxxxxxxx>]

Keir,

Here is a patch series I would like to have included into the
xen-4.1-testing.hg tree. These are all hypervisor changes. Roughly:
- some improvements to spinlock and bariers
- Jan's work on splitting up vcpu and domain structs
- some mm.c error handling fixes from you and Jan
- refactoring of hvm control register handling (Andre Przywara)
- refactoring of IO emulation (Christoph Egger)
- improvements to RCU and preempt.h
- GNTTABOP_swap (Wei Lui, Paul Durrant)
- small fixes here and there
- your fixes to wait queues

The patch series follows. I've commented '# Mod' next to the ones that
don't apply cleanly to tip (i.e. 23267:14416d8215d4). The others just move
cleanly from xen-unstable.hg. For those that don't apply cleanly, I've
attached the fixed version. It builds all the way (x86_32 and x86_64) and
so far so good on my testing.

(I couldn't think of a better way to deal with the modified patches than
straight attachment, but let me know if there is a better known method).

Thanks a lot,
Andres
