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

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.
