From 1fc8b4ef4e1a0d6f2e16581716a4ae6e16ad3a76 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 2 Nov 2005 14:48:36 +1100 Subject: [PATCH] powerpc: Merge (move) numnodes.h and sparsemem.h The ppc64 versions of numnodes.h and sparsemem.h can be safely moved to asm-powerpc with no changes apart from changing the #define to the standard _ASM_POWERPC_ form. There are no ppc32 versions of these files, because they only have any effect if CONFIG_SPARSEMEM is enabled, which it never can be on ppc32. Built and booted on pSeries (POWER5), built for 32-bit powermac.
