    Subject[PATCH 0/6] KVM support for TSC scaling
    Hi Avi, Marcelo,

    here is the patch-set to implement the TSC-scaling feature of upcoming
    AMD CPUs. When this feature is supported the CPU provides a new MSR
    which holds a multiplier for the hardware TSC which is applied on the
    value rdtsc[p] and reads of MSR 0x10. This feature can be used to
    emulate a given tsc frequency for the guest.
    Patch 1 is not directly related to this patch-set because it only fixes
    a bug which prevented me from testing these patches. In fact it fixes
    the same bug Andre sent a patch for. But after the discussion about his
    patch he told me to just post my patch and thus here it is.
