    Subject[PATCH -tip 0/4] kvm: Use rcuwait for vcpu blocking
    Date
    Hi,

    The following is an updated revision of the kvm vcpu to rcuwait conversion[0],
    following the work on completions using simple waitqueues.

    Changes from then:
    - patch 2: Make rcuwait_wake_up() propagate the return value from
    wake_up_process - Sebastian and Peter.

    - patch 3:
    o Added mips changes I missed.
    o Fixed broken compilation on power, adding the vcore bits that
    kvm-hv uses (a vcore blocking when all vcpus are blocked) - Paolo.
    o Use TASK_IDLE instead of TASK_INTERRUPTIBLE - Peter.

    - patch 4: fixed swait function name typo.

    This has only been run tested on x86 but compile tested on mips, powerpc
    and arm32.

    This series applies on top of current -tip, which has the required rcuwait
    api extension.

    Thanks!
