[PATCH] Move read_mostly definition to asm/cache.h

Browse source 
Seems like needless clutter having a bunch of #if defined(CONFIG_$ARCH) in
include/linux/cache.h.  Move the per architecture section definition to
asm/cache.h, and keep the if-not-defined dummy case in linux/cache.h to
catch architectures which don't implement the section.

Verified that symbols still go in .data.read_mostly on parisc,
and the compile doesn't break.
