[PATCH] V5 ia64 SPARSEMEM - conditional changes for SPARSEMEM
This patch introduces the conditional changes required for the three
memory models. With [patch 1/4] there are three memory models; FLATMEM,
DISCONTIG and SPARSEMEM. Also a new arch include file sparemem.h is
introduced for defining SPARSEMEM parameters.
