Programs using /proc/kpageflags need to know about the various flags. The <linux/kernel-page-flags.h> provides them and the comments in the file indicate that it is supposed to be used by user-level code. But the file is not installed. Install the headers and mark the unstable flags as out-of-bounds. The page-type tool is also adjusted to not duplicate the definitions Signed-off-by: Ulrich Drepper <drepper@gmail.com> Acked-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Acked-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
