    I believe it should be just these two commits, and the first is
    probably optional as the second makes it mostly redundant for the KVM
    case. Fengguang's 0day bot is watching this tree, so I expect to get
    success/failure results fairly shortly for various build tests at
    least.

    As noted, the first (need_resched) patch took our observed
    RCU latencies down from 5-10 seconds to 160ms, while the second one
    that we're working on now took it down to 40ms.[unhandled content-type:application/x-pkcs7-signature]
