X-Git-Tag: v3.2.20~5
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3798a7b34a19617eda5ce4b3025634b93b638de9;p=karo-tx-linux.git

kbuild: install kernel-page-flags.h

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
