Platform numbers

Hi y'all,

Are the platform numbers in asm-ppc64/processor.h private to Linux? Or do 
firmware/hardware know about them?

For pseries/pmac/maple it looks like we just assign them based on OF 
properties. For iSeries we check in the naca. I don't see where BPA gets 

The reason I ask is PLATFORM_MAPLE is currently 0x0500 which means we can't 
(easily) do any bit mask based trickery on platform numbers.
