297142 hyperv: Factor out snprinf_hv_guid() Submitted by: Ju Sun <junsu microsoft com> Reviewed by: Dexuan Cui <decui microsoft com>, sephe MFC after: 1 week Sponsored by: Microsoft OSTC Differential Revision: https://reviews.freebsd.org/D5651 297143 hyperv/vmbus: Implement bus_child_pnpinfo_str method Submitted by: Jun Su <junsu microsoft com> Sponsored by: Microsoft OSTC Differential Revision: https://reviews.freebsd.org/D5669 297176 hyperv/evttimer: Use an independent message slot so that it can work Using the same message slot as the other types of the messages has the side effect that the event timer message could be deferred to the swi threads to run (lacking of trapframe and the original code didn't even handle that, so the event timer was actually broken). As of this commit we use an independent message slot for event timer, so that we could handle all of event timer messages in the interrupt handler directly. Note, the message slot for event timer is still bind to the same interrupt vector as the other types of messages.
