ddccf307a3 [SCSI] mvsas: increase port type detection delay to suit Seagate's 10k6 drive ST3450856SS 0003
I increased the delay step by step until loading of mvsas
reliably detected the drive 200 times in sequence. A much better
approach would be to monitor the hardware for some flag which
indicates that port detection has finished, but I do not have any
hardware documentation.

We do not know what type the arch uses to implement u64.

1fce5e5da0 [SCSI] mvsas : interrupt handling
When a slot is busy, we will not free this slot until slot reset is
completed.  When unplugged the disk, we should release all command
tasks with unplugged port that have been sent.

If MVS_USE_TASKLET is defined, we can enable tasklet. Default is off.
