Ben,
Please consider this accessor routine which hides the details
of the map.

I'd much prefer:
static inline irq_hw_number_t virq_to_hw (unsigned int virq)
{
return irq_map[virq].hwirq;
}
I've grown to dislike the CR between the return type and the function
name (I used to do that too) and it seems that this opinion is shared by
Linus (there was an old thread on lkml about it).
Cheers,
Ben.

And while we're at it: no space before parenthesis in a function
declaration/definition.

Here is an updated version.
-Geoff
This adds an accessor routine virq_to_hw() to the
virq routines which hides the implementation details
of the virq to hwirq map.
