Subject: [PATCH 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.
