Sponsored by: Microsoft OSTC Differential Revision: https://reviews.freebsd.org/D6382 300101 hyperv/vmbus: Use unsigned long for event bits. And move base channel id calculation out of inner loop. This prepares for more event processing optimization. MFC after: 1 week Sponsored by: Microsoft OSTC Differential Revision: https://reviews.freebsd.org/D6384 300102 hyperv/vmbus: Reduce the # of event loops by recording event flag count Use vmbus softc to save vmbus per-cpu data. More stuffs will be moved into vmbus softc. MFC after: 1 week Sponsored by: Microsoft OSTC Differential Revision: https://reviews.freebsd.org/D6403 300105 hyperv/vmbus: Use atomic swap and flsl to process event flags Greatly reduce the locked instructions and reduce number of inner loops.
