* scsi: smartpqi: fix time handlingArnd Bergmann2017-05-14
| | | | | | | | | | | | | | | | | | | | | commit ed10858eadd4988260c6bc7d75fc25176342b5a7 upstream. When we have turned off RTC support, the smartpqi driver fails to build: ERROR: "rtc_time64_to_tm" [drivers/scsi/smartpqi/smartpqi.ko] undefined! This is easily avoided by using the generic 'struct tm' based helper rather than the RTC specific one. While fixing this, I noticed that even though the driver uses time64_t for storing seconds, it gets them from the old 32-bit struct timeval. To address this, we can simplify the code by calling ktime_get_real_seconds() directly.

* scsi: smartpqi: raid bypass lba calculation fixkevin Barnett2016-09-19
| | | | | | | | | | | | In the ioaccel path, the calculation of the starting LBA for READ(6)/WRITE(6) SCSI commands does not take into account the most significant 5 bits of the LBA: it only uses the least significant 16 bits of the starting LBA.
