We have received reports on power systems not running irqbalance where all interrupts are being routed to CPU0 rather than being interleaved by default across the system. Current firmware only allows either sending interrupts to all CPUs or sending them to one CPU. The following two patches address this issue by fixing the mask used in generic code and by fixing the check for the "all" setting in the pseries code.
