SMP support requires CPU hotplugging which MIPS currently doesn't support. As implemented in this patch cache and tlb flushing will also be invoked with interrupts disabled so smp_call_function() will blow up in charming ways. My request to move the cache and tlb flushing code was ignored but since this matter will need revisiting anyway and hibernation is a very useful feature I decieded to take the patch but limit hibernation to !SMP. Thanks folks! Ralf
