With this, together with your previous patch ("x86:
irq_move_cleanup_interrupt() must ignore legacy vectors") I can't hit previous
IRQ setup problem (at least for few tries).

But it still doesn't solve original problem - after suspend system temperature
goes high, apparently only CPU0 is online.
If I pin some domain vCPU to non-0 CPU before suspend, I hit ASSERT() on resume:
(XEN) Finishing wakeup from ACPI S3 state.
