Merge tag 'usercopy-v4.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull hardened usercopy fixes from Kees Cook:

 - inline copy_*_user() for correct use of __builtin_const_p() for
   hardened usercopy and the recent compile-time checks.

 - switch hardened usercopy to only check non-const size arguments to
   avoid meaningless checks on likely-sane const values.

 - update lkdtm usercopy tests to compenstate for the const checking.
