From 302616911da8e868d3f1a00dce517ca30b0e065d Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Fri, 6 Apr 2012 14:47:35 +0200 Subject: [PATCH] x86: Drop obsolete ARCH_BOOTMEM support x86 unconditionally uses NO_BOOTMEM so there is no use of the HAVE_ARCH_BOOTMEM support as mm/bootmem.c is the only file referencing this symbol. bootmem_arch_preferred_node() is the function referred in the mm/bootmem.c code and can thuis be dropped too. x86 was the sole user of HAVE_ARCH_BOOTMEM - so there is an opportunity to clean up a little in mm/bootmem.c too if we do not expect other users to emerge.
