Certainly Sparc and MIPS shouldn't check it if they don't set it.
For Alpha, I do want to easily discriminate between device, timer,
and inter-processor interrupts. I'm currently (ab)using the i386
CPU_INTERRUPT_SMI name for the IPI; I could abuse, say, FIQ for
my timer bit, but it seems nicer to simply keep the TIMER name.
