If you look at the irq handlers you'll see that most don't use the regs
parameter
and there have been talks about removing it altogether from the kernel.
Also,
if you think about the irq replaying scheme of Adeos and how you would
implement
saving the regs for every (to be) replayed interrupt, maybe you'll see
the point of
doing only the necessary reg saving in Adeos.
