I consider the spinlock thing a bugfix. I consider the new irq code very
more robust than the last one.

So they are really lucky.

Infact is not very different but is cleaner more robust and simpler and
this is the reason I think it should be put in.

If it' s really needed yes. The point is why not to put the wrapper in the
irq arch specific code of Amiga port? Is 2.1.119 uptodate with the latest
Amiga stuff? I am going to take a look to the Amiga irq stuff to
understand if it would be very tricky to put the wrapper there.
