linux-next: manual merge of the security tree with Linus' tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi James,

Today's linux-next merge of the security tree got conflicts in
security/keys/keyring.c and security/keys/process_keys.c between commit
9a56c2db49e7 ("userns: Convert security/keys to the new userns
infrastructure") from Linus' tree and commit 96b5c8fea6c0 ("KEYS: Reduce
initial permissions on keys") from the security tree.

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

Cheers,
