Hi Thomas,

I briefly tested this patch and it appears to also solve the issues I
mentioned.

I think both solutions would work. The only drawbacks I see in using
this patch over the other one are that this patch involves a bit more
locking in synchronize_irq() and irq_finalize_oneshot() (for non-oneshot
irqs), and that the oneshot mechanism is used for non-oneshot threads.

Thanks,
Ido.
