Rafael and Guo-Fu,
The following change to address the compile error that you noted is
slightly different than what you suggested but should fix what you
found.

Fix CIFS compilation with CONFIG_KEYS unset

If CONFIG_KEYS is unset, fs/cifs/sess.c doesn't build due to key_revoke()
being undefined.  Fix that.
