Subject: [PATCH v2 0/4] KVM: x86: kvmclock cleanups for Hyper-V TSC page

This implements the plan that we discussed at KVM Forum.  Patch 3
implements a new function that returns the current value of kvmclock as
read by the guest.  The function is then used to provide the Hyper-V
time reference counter.  Now that the reference counter is synchronized
with kvmclock, the TSC page can be supported nicely.

Paolo

v2->v3: use TSC page information to compute time reference counter value
	fixed case where TSC seq is 0xFFFFFFFE

Paolo Bonzini (4):
  KVM: x86: always fill in vcpu->arch.hv_clock
  KVM: x86: initialize kvmclock_offset
  KVM: x86: introduce get_kvmclock_ns
  KVM: x86: Hyper-V tsc page setup
