From: Ulrich Drepper <drepper@akkadia.org>

commit 9295b7a07c859a42346221b5839be0ae612333b0 upstream.

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
