Oh sorry, I copied the patch from various other architectures I touched
at the same time. I have been wading throug all architectures to
convert them to asm-generic/hardirq.h and the generic ack_bad_irq and
sent out lots of patches for it. A couple of architectures do count
bad irqs instead of just printing a message, but even those counters
could be unified. The only genirq architectecture that does something
weird in ack_bad_irq is mips.
