Subject: [PATCH] fix the interrupt loss problem on powerpc IPIC
(2.6.25-2.6.28)
Description: The interrupt pending register is write 1 clear. If
there are more than one external interrupts pending at the same
time, acking the first interrupt by reading pending register then OR
the corresponding bit and write back to pending register will also
clear other interrupt pending bits. That will cause loss of
interrupt.
