Right, I was thinking about
if (irq >= 0 && irq < IOAPIC_NUM_PINS) {
Should return MASKED if irq is outside the acceptable range?
Is this ever can be false? Should we BUG() if irq is out of range?
Yes, the number ultimately comes from userspace.
So may be -EINVAL should be returned to userspace?
Mmm, not sure. An out-of-bounds number here could be caused by
userspace generating the wrong irq line number, or by the guest
misconfiguring interrupts.
We should error out on userspace bugs, but not guest bugs.
