All the system device suspend and the actual CPU power-off still happens 
with CPU interrupts disabled.

It's just that the regular two-phase device suspend code now runs first 
with interrupts enabled (the regular "->suspend()" callback), and then the 
second phase runs with the CPU still having interrupts on (and taking 
timer interrupts), but with the actual device interrupts disabled.
