Todo:

  - Chain handler optimizations for Mac,
  - Removal of legacy code inside #ifndef CONFIG_GENERIC_HARDIRQ,
  - Proper patch submission emails,
  - Get it merged (For 3.3? Or even 3.2?).

Oh, I almost forgot: testing ;-)! So far I tested it on Atari (ARAnyM)
and Amiga only.

Thanks for testing and feedback!
