SVN rev 218427 on 2011-02-08 01:49:30Z by marcel
In arm_get_next_irq(), use the last IRQ argument in order to prevent
a hard hang due to an interrupt storm or stuck interrupt pin. We
return the next IRQ that is larger than the last one returned and
in doing so give all interrupts a fair chance of being handled.
Consequently, we're able to break into the kernel debugger in such
an event.
