Here is a new version of this series.
I am definitely leaving any warp calculations out, as Jeremy wisely
points out that Chuck Norris should perish before we warp.
Also, in this series, I am using KVM_GET_SUPPORTED_CPUID to export
our features to userspace, as avi suggets. (patch 4/7), and starting
to use the flag that indicates possible tsc stability (patch 7/7), although
it is still off by default.
Glauber Costa (7):
Enable pvclock flags in vcpu_time_info structure
Add a global synchronization point for pvclock
change msr numbers for kvmclock
export paravirtual cpuid flags in KVM_GET_SUPPORTED_CPUID
Try using new kvm clock msrs
don't compute pvclock adjustments if we trust the tsc
Tell the guest we'll warn it about tsc stability

I'll rebase on top of these if they get pulled.
And obviously, there is no point in checking for warp if Chuck Norris
has perished. I happen to have a special place in my heart for nunchaku
masters despite the fact that this created a generation of teenagers who
insisted they were called numb-chucks.
