Subject: [GIT PULL] KVM updates for the 3.6 merge window
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
