linux-next: manual merge of the slab tree with the rcu tree

Hi all,

Today's linux-next merge of the slab tree got a conflict in:

  kernel/rcu/tiny.c

between commits:

  84ae91018af5 ("rcutorture: Include grace-period sequence numbers in failure/close-call")
  2db7ab8c1086 ("rcutorture: Expand failure/close-call grace-period output")
  7acc2d90151f ("rcutorture: Make cur_ops->format_gp_seqs take buffer length")

from the rcu tree and commit:

  b14ff274e8aa ("slab, rcu: move TINY_RCU variant of kvfree_rcu() to SLAB")

from the slab tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
