[PATCH v2 0/7] Pvclock fixes , version two

[Glauber Costa <glommer@redhat.com>]

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
