Rather than a giant ifdef in the body of do_IRQ(), including a
dangling else, move the irq stack logic into a separate routine and
do the ifdef there.

The guts of do_IRQ() isn't really the right place to be documenting
the ppc_md.get_irq() interface. So move the comment into machdep.h

We should no longer have any irq code that needs __do_IRQ(), so
remove the fallback to __do_IRQ().

Should be desc->handle_irq. It's fixed in a later patch, but this breaks

Ah crud, thanks for spotting it. That's an artifact of me reordering the

Not sure. Looks like the 64-bit configs all turn it on, and all but one
or two of the 32-bit configs don't.

Yeah, but do they have a reason not to turn it on? Having irqstacks
is a lot safer than no having it because the stack useage is a lot more
predictable. And not having to maintain two codepathes is also a
benefit all by itself.

I think Ben, Paul and I had discussed just universally enabling it.
Can't remember why Ben hadn't done that yet.
