KVM: Fix reboot on Intel hosts
When we reboot, we disable vmx extensions or otherwise INIT gets blocked. If a task on another cpu hits a vmx instruction, it will fault if vmx is disabled. We trap that to avoid a nasty oops and spin until the reboot completes. Problem is, we sleep with interrupts disabled. This blocks smp_send_stop() from running, and the reboot process halts. Fix by enabling interrupts before spinning. KVM-Stable-Tag. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
