"powerpc: Properly handshake CPUs going out of boot spin loop"
Would cause a miscalculation of the hard CPU ID. It removes breaking
out of the loop when finding a match with a processor, thus the "i"
used as an index in the intserv array is always incorrect
This broke interrupt on my PowerMac laptop.
