Merge tag 'lkdtm-v4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull lkdtm update from Kees Cook:
 "Fix rebuild problem with LKDTM's rodata test"

[ This, and the usercopy branch, both came in before the merge window
  closed, but ended up in my 'need to look more' queue and thus got
  merged only after rc1 was out ]
