Hello NetBSD hackers,
I have read over there  that cpu_intr_p() should return true if
curcpu() is currently "in the context of a hardware interrupt".
Does this mean that cpu_intr_p() should return true when CPU is in
exception handler (tlb miss handler, tlb fault handler, division by
zero etc) as well as in exception caused by an interruption? Or Should
it only return true for true interruption like UART or timer interrupt
and not for exception handlers not related to an interruption?
I also had a look at this thread  but it did not provide me with
much information, except that I could just implement it as "return
false;", is it still true?
