[PATCH] FRV: improve FRV's use of generic IRQ handling
Improve FRV's use of generic IRQ handling:
(*) Use generic_handle_irq() rather than __do_IRQ() as the latter is obsolete.
(*) Don't implement enable() and disable() ops as these will fall back to
using unmask() and mask().
(*) Provide mask_ack() functions to avoid a call each to mask() and ack().
(*) Make the cascade handlers always return IRQ_HANDLED.
(*) Implement the mask() and unmask() functions in the same order as they're
listed in the ops table.
