The disable_nonboot_cpus() needs IPIs to work. But prior to
calling disable_nonboot_cpus(), the IPIs are disabled in
dpm_suspend_noirq().

During suspend, all interrupts including IPI will be disabled. In this case,
the suspend process will hang in SMP. To prevent this, pass the flag
IRQF_NO_SUSPEND when requesting IPI irq.

During suspend, all interrupts including IPI will be disabled. In this case,
the suspend process will hang in SMP. To prevent this, pass the flag
IRQF_NO_SUSPEND when requesting IPI irq.
