i am thinking of sending a new patch, with,

1) IRQF_SHARED removed from sni/{a20r.c,pcit.c,rm200.c}
2) IRQF_SHARED kept in,
        kernel/cevt-r4k.c
        dec/setup.c
        pmcs-msp71xx/msp-time.c
        loongson2ef/lemote-2f/irq.c
    and use handler as dev_id in those

Let me know if you have any other thoughts.
