    Subject[PATCH] Install kernel-page-flags.h
    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.

    The patch below installs the headers and marks the unstable flags as
    out-of-bounds.
