eisa_add_intr() which now takes an additional arguement (one of EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE). The flag RR_SHAREABLE has no effect when passed to bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as the eisa_alloc_resource() call (bus_alloc_resource method) now deals with this flag directly, depending on the device ivars. This change does nothing more than move all the 'shared = inb(foo + iobsse)' nonesense to the device probe methods rather than the device attach. Also, print out 'edge' or 'level' in the IRQ announcement message. Reviewed by: dfr
