This seems to encourage sloppy coding: The only variant you allow is the one
that corresponds to Linux's spin_lock_irqsave(), which is generally discouraged
in all places where you know if you need to disable interrupts or not.
IMHO the default should be a version that only allows locks that don't get
taken at IRQ time and consequently don't require saving the interrupt flags.
