Subject: [GIT PULL] KVM updates for the Linux 3.1 merge window
Linus, please pull from
git://git.kernel.org/pub/scm/virt/kvm/kvm.git kvm-updates/3.1
to get the KVM updates for the current merge window. Major features
include powerpc hypervisor-mode support and an initial version of VMX
nesting. Other changes include steal time support (both host and
guest), faster MMIO, and additional cpu features exposed to the guest
(most importantly SMEP).
[The steal time changes touch the core scheduler; these changes have
been acked by Peter]
