PATCH 1/1 m68knommu: enable_irq/disable_irq

mach_enable_irq/mach_disable_irq are never actually set, so let's remove them.

Btw, is it really intentionally that enable_irq/disable_irq are no-ops on m68knommu?

No, I think they should be implemented. It would clean up some driver irq ugliness in some of the m68knommu arch specific drivers.

Greg

Any chance you could investigate using the kernel/irq/ framework for m68knommu? It's one of the few architectures not using that code yet.
