[patch] use generic topology macros where possible

[Matthew Dobson <colpatch@us.ibm.com>]

Linus,
	This patch modifies the ppc64 and alpha topology.h files to use the 
generic (non-NUMA) macros in the non-NUMA cases for both architectures. 
  Currently, the non-NUMA macros are defined in 3 places (asm-generic, 
asm-ppc64, and asm-alpha), making it more difficult to keep them all 
in-sync.  It even cuts out a whopping *9* lines of code! ;)

This patch applies cleanly alongside the other topology fix I just posted.

Please apply...

Cheers!
