2016-04-15mpt3sas: Remove usage of 'struct timeval'Tina Ruchandani1-4/+4
'struct timeval' will have its tv_sec value overflow on 32-bit systems in year 2038 and beyond. This patch replaces the use of struct timeval for computing mpi_request.TimeStamp, and instead uses ktime_t which provides 64-bit seconds value. The timestamp computed remains unaffected (milliseconds since Unix epoch).

2016-04-15pm80xx: Remove bogus address masking in pm8001_ioremap()David Daney1-2/+0
It is unclear what the original intent of the masking was, but it is clearly incorrect to truncate a physical address before calling ioremap(). On systems where there are valid physical address bits above bit-31 (arm64 for example) the result is an eventual OOPs when initializing the driver. Remove the bogus code to fix it.

2016-04-15qla2xxx: Remove use of 'struct timeval'Tina Ruchandani1-3/+2
struct register_host_info stores a 64-bit UTC system time timestamp. This patch removes the use of 'struct timeval' to obtain that timestamp as its tv_sec value will overflow on 32-bit systems in year 2038 beyond. The patch uses ktime_get_real_seconds() which returns a 64-bit seconds value.

This patch fixes the ITCT table setup as it should be configured differently for SAS and SATA devices. For SATA disks there is no need to set qw2 (already zeroed). Also, link parameters for Bus inactive limit, max connection time limit, and reject to open limit timers parameters are changed to match global config register, MAX_CON_TIME_LIMIT_TIME, as recommended by hw team.

This patch adds support for directly attaching SATA disks to phy 4-8. The problem was that only registers concerned with phy 0-3 were being considered in sata_int_v2_hw().

When we are in connection recovery and the internal command timer on a request pops, either the scsi_cmnd->device or scsi_cmnd->device->host back pointers may be NULL as the device that the command that the request was submitted on may have been subsequently reaped due to the connection recovery. This can cause one or both of the pointers above to be NULL and cause a system crash if we try to return the command to the midlayer. Instead, double check the pointers before the return to the midlayer so as to prevent the crash and let the upper layers finish the session recovery and rediscover the device.

On larger installations it is useful to disable automatic LUN scanning, and only add the required LUNs via udev rules. This can speed up bootup dramatically.
