linux-next: manual merge of the userns tree with the security tree

Hi Eric,

Today's linux-next merge of the userns tree got a conflict in
security/integrity/ima/ima_policy.c between commit 07f6a79415d7 ("ima:
add appraise action keywords and default rules") from the security tree
and commit 8b94eea4bfb8 ("userns: Add user namespace support to IMA") from
the userns tree.

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