[PATCH] unify pfn_to_page: x86_64 pfn_to_page
x86_64 can use generic funcs. For DISCONTIGMEM, CONFIG_OUT_OF_LINE_PFN_TO_PAGE is selected. Signed-off-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Cc: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
