The generic definition is the one to use - we used to allow
__cpu_raise_softirq from outside IRQ context, but all RISC architectures
ended up with code as follows:
save + disable irqs
In the latest kernels, you will notice that __cpu_raise_softirq is always
within an IRQ protected region (thanks to Andrea for that work), so there
is no reason for it to protected itself from interrupts. Hence the comment
* This function must run with irq disabled!
