Subject[GIT PULL] KVM updates for 2.6.26rc
Date
Linus, please pull the kvm updates for 2.6.26 from the repo and branch

git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git kvm-updates-2.6.26

The changes include new host architectures (s390, ia64, and ppc 44x),
paravirtualized kernel support, support for the new AMD NPT and Intel VPID
hardware virtualization extensions, large host page support, scalability
improvements, a PIT model, a performance tracing system (kvmtrace), as well
as the usual guest support improvement and minor speedups.

Note that a few changes to s390 and ppc arch code are included; these have
been acked by the respective maintainers.
