3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Roland Dreier <[email protected]> commit bf0053550aebe56f3bb5dd793e9de69238b5b945 upstream. My draft of SPC-4 says: If the PAGE CODE field is not set to zero when the EVPD bit is set to zero, the command shall be terminated with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the additional sense code set to INVALID FIELD IN CDB.
