    [PATCH] FRV: improve FRV's use of generic IRQ handling · 88d6e199
    David Howells authored
    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     (*) Use generic_handle_irq() rather than __do_IRQ() as the latter is obsolete.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.
