[2.6 patch] unexport phys_proc_id and cpu_core_id

[Adrian Bunk <bunk@stusta.de>]

Back in January, Andi Kleen added EXPORT_SYMBOL(phys_proc_id), stating:
  This is needed for the powernow k8 driver to manage AMD dual core 
  systems.

This EXPORT_SYMBOL was never used.

I asked him on 13 Mar 2005 whether it's really required, but he didn't 
answer to my email.

2.6.12-rc3 adds cpu_core_id with a similarly unused 
EXPORT_SYMBOL(cpu_core_id).

It's OK to export symbols when these exports are required, but unless 
someone can explain why they are required now, they should be removed 
before 2.6.12 and then re-added when they are actually used.
