From 867c5b5292583b1e474cbbcb4c77f09bfca3903c Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Tue, 3 Mar 2009 14:10:12 +0200 Subject: x86: set_highmem_pages_init() cleanup Impact: cleanup This patch moves set_highmem_pages_init() to arch/x86/mm/highmem_32.c. The declaration of the function is kept in asm/numa_32.h because asm/highmem.h is included only if CONFIG_HIGHMEM is enabled so we can't put the empty static inline function there.
