I don't think it does. There are two pieces to the problem
a) Not dying horribly
b) Handling it elegantly
b) is driver specific (NAPI etc) and I think well understood to the point
its being used already for performance reasons
a) is as simple as
if(stuck_in_irq(foo) && irq_shared(foo))
{
disable_real_irq(foo);
timer_fake_irq_foo();
}
We know spoofing a shared irq is safe.
