SCSI misc on 20180131

Browse Source 
This is mostly updates of the usual driver suspects: arcmsr,
 scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
 hisi_sas.  We also have a rework of the libsas hotplug handling to
 make it more robust, a slew of 32 bit time conversions and fixes, and
 a host of the usual minor updates and style changes.  The biggest
 potential for regressions is the libsas hotplug changes, but so far
 they seem stable under testing.
