Also at tags/for-linus, but request-pull chose this other tag for some reason.

Merge branch 'kvm-ppchv-next' of git:// into kvm-next (2014-03-29 15:44:05 +0100)

No other changes expected for this merge window.



PPC and ARM do not have much going on this time. Most of the cool stuff,
instead, is in s390 and (after a few releases) x86.

ARM has some caching fixes and PPC has transactional memory support
in guests. MIPS has some fixes, with more probably coming in 3.16 as
QEMU will soon get support for MIPS KVM.

For x86 there are optimizations for debug registers, which trigger on
some Windows games, and other important fixes for Windows guests. We now
expose to the guest Broadwell instruction set extensions and also Intel
MPX. There's also a fix/workaround for OS X guests, nested virtualization
features (preemption timer), and a couple kvmclock refinements.

For s390, the main news is asynchronous page faults, together with
improvements to IRQs (floating irqs and adapter irqs) that speed up
virtio devices.
