Subject[PATCH 001/003]Fix unify mapping from pxm to node id.
I'm sorry for my lazy work.
There were some compile errors for i386 and ia64. Not only Paul-san,
Bob-san and Andy-san also sent me result of complile or patches.
(Thanks a lot!)
To tell all of here and summarize what was wrong,
I'll repost all patches to solve them. These are for 2.6.16-rc1-mm3.

Andrew-san. Please apply.

----------------
This is for fix unification from pxm to node id against i386.
acpi_numa_processor_affinity_init() and other 3 function was defined for
x86-64 and ia64. But i386 doesn't use them.
This is just dummy function for compile.
And some of garbages are removed.
