[PATCH][0/2] ppc64 pre/post boot memory macros

[Joel Schopp]

I'm sending two patches for review and passing upstream.  The basic idea 
is that these patches put in place some macros such that memory 
management can be easily split into pre and post boot.  This is based on 
the work of Mike Kravetz and Dave Hansen.  It should be harmless, as the 
new macros are currently defined to the same thing the old macros were. 
  It is also isolated to ppc64 files, so the other arch guys don't need 
to worry.

Ultimatly my motivation is to move toward hotplug memory.  Acceptance of 
these patches will allow us to carry smaller patches out of mainline and 
ease our development greatly.

Comments/feedback/flames welcome.  Patches against 2.6.9-rc3 and have 
been boot tested on Power5 LPAR.
