    Merge branch 'uaccess-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
    
    Pull uaccess fixes from Al Viro:
     "Fixes for broken uaccess primitives - mostly lack of proper zeroing
      in copy_from_user()/get_user()/__get_user(), but for several
      architectures there's more (broken clear_user() on frv and
      strncpy_from_user() on hexagon)"
