[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. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
