63 * The next 16 interrupts are for board specific purposes. Since
64 * the kernel can only run on one machine at a time, we can re-use
65 * these. If you need more, increase IRQ_BOARD_END, but keep it
66 * within sensible limits. IRQs 49 to 64 are available.

72 * Figure out the MAX IRQ number.
74 * Neponset, SA1111 and UCB1x00 are sparse IRQ aware, so can dynamically
75 * allocate their IRQs above NR_IRQS.
77 * LoCoMo has 4 additional IRQs, but is not sparse IRQ aware, and so has
78 * to be included in the NR_IRQS calculation.
