Xiangliang Yu 0b15fb1fdf [SCSI] mvsas: add support for Task collector mode and fixed relative bugs
1. Add support for Task collector mode.
2. Fixed relative collector mode bug:
   - I/O failed when disks is on two ports
   - system hang when hotplug disk
   - system hang when unplug disk during run IO
3. Unlock ap->lock within .lldd_execute_task for direct mode to
   improve performance

Srinivas 9dc9fd9484 [SCSI] mvsas: fix hot plug handling and IO issues
This patch adds a bunch of fixes

1. Reduce sg table size to 64 (SG_MX) instead of default SG_ALL
2. clear task lists on phy down events
3. release all tasks on port deformation
4. release current task for device gone notification
5. Add sata abort handing
6. Add 10ms delay to each port reset (currently done serially and with
   interrupts disabled)

[jejb: whitespace fixes and clean ups plus added description
       added dummy 94xx_clear_srs_irq function just to prevent the
       mismatch in the mvs_dispatch structure killing 94xx cards]
