ia64 SN update

David, here's a patch to update SN support in the ia64 tree. I had to make a few mods outside arch/ia64/sn and include/asm-ia64/sn to get CONFIG_IA64_SGI_SN2 to compile.

This is the first time I've used bitkeeper to generate a patch, so hopefully I got it right, but please let me know if you need another format. Here's the diffstat for the non-SN files:

 arch/ia64/Makefile                        |    7
    update SN subdirs
 arch/ia64/kernel/sal.c                    |    2
    make ia64_sal_handler_init non-static
 include/asm-ia64/machvec_sn2.h            |  102 -
    update SN2 machvec entries
 include/asm-ia64/mmzone.h                 |   32
    add SN2 discontig support
 include/asm-ia64/numa.h                   |    2

add new local_nodeid() macro

Thanks,
Jesse

Do you really need this. kbuild contains the above rules, and if it does not work deleting the above lines I would like to know.

Same comment for sn1 and sn2.

Also could you please delete inclusion of Rules.make, it has disappeared from Linus's tree.
