Linus, please pull from the repo and tag at:
git://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/kvm-3.6-1
to merge the KVM updates for the 3.5 merge window.
Highlights include
- full big real mode emulation on pre-Westmere Intel hosts (can be disabled
with emulate_invalid_guest_state=0)
- relatively small ppc and s390 updates
- PCID/INVPCID support in guests
- EOI avoidance; 3.6 guests should perform better on 3.6 hosts on interrupt
intensive workloads)
- Lockless write faults during live migration
- EPT accessed/dirty bits support for new Intel processors

Ok, this caused conflicts with the s390 and ppc trees. I think I fixed
them correctly, but the respective arch people really should take a
look.

A quick peek at the merge commit looks allright, but Alex mentioned that
there's some more fallover that needs an actual patch to fix (the
changes to enforce a cleaner ASM syntax need to be applied to some new
code from Avi's tree that didn't actually trigger merge conflicts).
I'll follow up with Alex and send you the relevant patches if any.
Cheers,
Ben.

There was at least one, but Linus got it (I checked all the mentions of
VCPU_GPR). His merge resolution matches the one that has been in
linux-next for quite some time.
