Vmbus_synic_setup() is invoked via vmbus_intrhook -> vmbus_doattach -> smp_rendezvous. On !EARLY_AP_STARTUP (e.g., aarch64), SMP isn't functional in intrhooks and smp_rendezvous() will just call vmbus_synic_setup() on the boot processor. There's nothing that will initialize the pcpu data on every other AP. To fix it we need to use SI_SUB_SMP for vmbus_doattach(). With this patch the vmbus interrupt should work on all arm64 cpus on HyperV.
