General comment...
kernel/irq/* denote the virtual irq numbers "irq".
powerpc uses "virq" for the same.

Sometimes it is confusing that two different names is used
for the same thing.

The intent of this patch is to centralize access to a common data structure,
but this could also be a good candidate for a terminology shift if
this is considered.

"git grep virq" shows a lot of hits - especially in arm, powerpc.
So what I suggest is obviously only a small step in the direction
of using "irq" all over.
