Linus, the repo and branch
git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git kvm-updates-2.6.27
await your pulling pleasure. There's a fix for the kvmtrace ABI, a race
plugged in smp guests on i386 hosts, and a fix for the placement of
exception handlers used during host reboot.
Shortlog, diffstat, and diff follow.
