MIPS: SGI-IP27: micro-optimize arch_init_irq()
The function sets adjasted groups of bits in hub_irq_map by using
for-loops. There's a bitmap_set() function dedicated to do this.
Because [0, CPU_CALL_B_IRQ] and [NI_BRDCAST_ERR_A, MSC_PANIC_INTR]
ranges belong to the same machine word, bitmap_set() would boil down
to an inline wrapper in both cases, avoiding generating a loop, whth
the associate overhead.
