Argh!! I intended this to be a macro like this
#define enable_fiq(x)  enable_irq((x) + FIQ_START)
so that the constant is needed only at places where it is expanded.

This way different platforms can have their local irqs.h supply the constant,
where the macros are used.

Somehow I thought inline functions are more readable and assumed the
same macro'ish behaviour.

Will a macro variant of this be more useful ?

Thanks,
Venkat.
