m68k_handle_int() split in two functions: __m68k_handle_int() takes
pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs
*.
Places where we used to call m68k_handle_int() recursively with the same
pt_regs have simply lost the second argument, the rest is switched to
__m68k_handle_int().
The rest of patch is just dropping pt_regs * where needed.

Convert the generic irq code to use irq controller, this gets rid of the
machine specific callbacks and gives better control over irq handling without
duplicating lots of code.

Introduce irq controller and use it to manage auto vector interrupts.
Introduce setup_irq() which can be used for irq setup.

Correct the return type of handle_IRQ_event() (inconsistency noticed during
Xen development), and remove redundant declarations. The return type
adjustment required breaking out the definition of irqreturn_t into a
separate header, in order to satisfy current include order dependencies.

Patch claiming to remove enable_irq_nosync() had left it alive but killed
disable_irq_nosync() instead...

move the sanity check for NR_IRQS being no more than 1<<HARDIRQ_BITS from
asm-m68k/hardirq.h to asm-m68k/irq.h; needed since NR_IRQS is not necessary
know at the points of inclusion of asm/hardirq.h due to the rather ugly header
dependencies on m68k. Fix is by far simpler than trying to massage those
dependencies...

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!
