    Subject[PATCH v3 0/9] Steal time for KVM
    Date
    This patchset adds on the previous one, merging the suggestions
    made mainly by Gleb, Peter and Marcelo.

    SCHEDSTATS is now used when available to provide information about
    time spent on the runqueue for the cpu threads. Information to/from
    the guest is obtained using *_cached() functions, as suggested by Gleb.

    On the guest side, the two "prev_steal_time" variables are colapsed
    into a single one. Steal time accounting is also done inside
    update_rq_clock().

    Glauber Costa (8):
    KVM-HDR Add constant to represent KVM MSRs enabled bit
    KVM-HDR: KVM Steal time implementation
    KVM-HV: KVM Steal time implementation
    KVM-HV: use schedstats to calculate steal time
    KVM-GST: Add a pv_ops stub for steal time
    KVM-GST: KVM Steal time accounting
    KVM-GST: adjust scheduler cpu power
    KVM-GST: KVM Steal time registration

    Gleb Natapov (1):
    introduce kvm_read_guest_cached
