I rebased to 3.0-rc1 and added (not in that order):
  [10] m68k/irq: Add m68k_setup_irq_controller()
  [11] m68k/irq: Adding missing "irq" offset in m68k_setup_irq_controller()
  [12] m68k/irq: Fix auto and user chips and handlers
  [13] m68k/amiga: Refactor amiints.c
  [14] m68k/amiga: Convert Amiga to genirq
  [15] m68k/amiga: Optimize interrupts using chain handlers

It works on Amiga now, too. It can still use some optimizations in the
irq_{enable,disable,ack,mask,mask_ack,unmask} area, as my BogoMIPS
rating dropped by ca 2.5% and is now under 16, for a 25 MHz 68040.

BTW, the second warning on Atari is still there.
