Subject: linux-next: manual merge of the tip tree with the s390 tree

Hi all,

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

  arch/s390/lib/uaccess.c

between commit:

  cabc4abe8e36 ("s390/uaccess: remove uaccess_primary kernel parameter")

from the s390 tree and commit:

  ed79e946732e ("s390/uaccess, locking/static_keys: employ static_branch_likely()")

from the tip tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
