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.
