Subject[PATCH][RFT] noirqbalance still doesn't do anything
I didn't get a response to my other patch to do this so i'm guessing that 
people want a simpler patch(??) This one simply sets TARGET_CPUS to
cpu_callout_map instead of cpu_online_map so that when we finally do boot
we actually use the other cpus for servicing interrupts.

Only tested on 2way AMD/SMP booted with noirqbalance, interrupts get
distributed via apic bus arbitration.
