[PATCH] Altix update: io changes

From: Pat Gefre <pfg@sgi.com>

arch/ia64/sn/io/platform_init/sgi_io_init.c
   use numionodes instead of numnodes

arch/ia64/sn/io/sn2/klconflib.c
    find_lboard changes - generalized a number of the interface funcs

arch/ia64/sn/io/sn2/klgraph.c
    call the more general find_lboard funcs

arch/ia64/sn/io/sn2/ml_iograph.c
    call the more general lboard funcs

arch/ia64/sn/io/sn2/module.c
    lboard changes
    mod for headless/memless nodes

arch/ia64/sn/io/sn2/pcibr/pcibr_dvr.c
    isIO9 mod

arch/ia64/sn/kernel/setup.c
    headless/memless mod

include/asm-ia64/sn/klconfig.h
    generalized find_lboard funs
