It's useful to have access to struct ipic handle that just got created
in ipic_init().

For example, if we want to setup an external IRQ with out
a device node we need access ipic->irqhost to create the virtual to HW
IRQ mapping and to set the IRQ sense.  With this we can mimic the old
sense array concept that existed in arch/ppc.

Remove struct pt_regs * from all handlers.
Also remove the regs argument from get_irq() functions.
Compile tested with arch/powerpc/config/* and
arch/ppc/configs/prep_defconfig

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
