    irq: initialize nr_irqs based on nr_cpu_ids · 9332fccd

    Impact: Reduce memory usage.
    
    This is the second half of the changes to make the irq_desc_ptrs be
    variable sized based on nr_cpu_ids.  This is done by adding a new
    "max_nr_irqs" macro to irq_vectors.h (and a dummy in irqnr.h) to
    return a max NR_IRQS value based on NR_CPUS or nr_cpu_ids.
    
    This necessitated moving the define of MAX_IO_APICS to a separate
    file (asm/apicnum.h) so it could be included without the baggage
    of the other asm/apicdef.h declarations.
