From: Chen Baozi <baoz...@gmail.com>
evtchn_init() will call domain_max_vcpus() to allocate poll_mask, which
needs the max vCPU number returned by domain_max_vcpus(). On arm/arm64
platform, this number is determined by the vGIC the guest is going to
use, which won't be initialised until arch_domain_create() is finished.
