If the driver fails to retrieve information from the fw (could happen when the fw is not fully in its senses), the driver does nothing and change is not processed correctly by the driver Schedule host rescan in case of failure.

Driver uses scsi_scan_host to add new devices in the driver init path, which adds all the fw exposed devices. The drivers resorts to queue command checks to block out commands to _hidden_ devices. Use the hotplug handler code to add new devices during driver init and other areas, this is only for safw. For ARC scsi_scan_host will still apply.

Resolve luns checks the if a sdev is already present in the os to figure out if it needs to be removed. Internally the driver exposes HBA on bus 2 even though its bus 1 in the fw.

Driver attempts to perform a device scan and device add after coming out of reset. At times when the kdump kernel loads and it tries to perform eh recovery, the device scan hangs since its commands are blocked because of the eh recovery. This should have shown up in normal eh recovery path (Should have been obvious) Remove the code that performs scanning.I can live without the rescanning support in the stable kernels but a hanging kdump/eh recovery needs to be fixed.

aacraid passes the current time to the firmware in one of two ways, either as year/month/day/... or as 32-bit unsigned seconds. The first one is broken on 32-bit architectures as it cannot go past year 2038. Using timespec64 here makes it behave properly on both 32-bit and 64-bit architectures, and avoids relying on signed integer overflow to pass times into the second interface. The interface used in aac_send_hosttime() however is still problematic in year 2106 when 32-bit seconds overflow. Hopefully we don't have to worry about aacraid by that time.

During a PCI error recovery, if aac_check_health() is not aware that a PCI error happened and we have an offline PCI channel, it might trigger some errors (like NULL pointer dereference) and inhibit the error recovery process to complete. This patch makes the health check procedure aware of PCI channel issues, and in case of error recovery process, the function aac_adapter_check_health() returns -1 and let the recovery process to complete successfully. This patch was tested on upstream kernel v4.11-rc5 in PowerPC ppc64le architecture with adapter 9005:028d (VID:DID) - the error recovery procedure was able to recover fine.

The driver will attempt to restart the adapter, but the response is not checked in aac_command_thread. This allows the periodic sync to go thru and lead the driver to a hung state.
