I'm not keen on this. Normal IRQs can't reliably work, so why do you
even bother with this?
Yeah I agree but we need to support existing functionality for kgdb
roundup and sysrq backtrace using normal IRQs as well.
When has this become a requirement? I don't really see the point in
implementing something that is known not to work.
