First, figure out if the code in question should even be called
from those contexts, or if it's a bug if that happens.
Hard and soft IRQ contexts are basically interrupt handlers. If your
code is a "hello world" module, or if it's filesystem code, or
pretty much any part of the kernel that's not a device driver, it
probably should not be called from IRQ context.
