Fix interrupt distribution to multiple CPUs on systems with cascaded PICs.
Because slave PICs send all interrupts to their CPU 0 output line (which
is routed to a pin on the master PIC), changes to per-CPU register banks
like EOI on the slave PIC must be accessed for CPU 0, instead of the
CPU actually processing the interrupt.
