OK, with 3/5 dropped 4/5 get a trivial conflict (removal of function in 4/5

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-davem

Shortlog:
Al Viro (4):
      separate kernel- and userland-side msghdr
      {compat_,}verify_iovec(): switch to generic copying of iovecs
      fold verify_iovec() into copy_msghdr_from_user()
      bury skb_copy_to_page()
