Obviously if x86_64 doesn't even build your changes, that is one such
platform. Also, is grep not working on your computer?
Platforms are absolutely no required to have this define, zero is the
only valid "no IRQ" which is portable in any way.
This is an old and tired topic, portable code does not use NO_IRQ, and
that's simply the end of it.
