3d38f00c41 scsi: hpsa: separate monitor events from rescan worker 
create new worker thread to monitor controller events
 - both the rescan and event monitor workers can cause a rescan to occur
   however for multipath we have found that we need to respond faster
   than the normal scheduled rescan interval for path fail-overs.
 - getting controller events only involves reading a register, but the
   rescan worker can obtain an updated LUN list when there is a PTRAID
   device present.
 - move common code to a separate function.
advantages:
 - detect controller events more frequently.
 - leave rescan thread interval at 30 seconds.

58eaffe54b scsi: aacraid: Set correct Queue Depth for HBA1000 RAW disks 
The default queue depth for non NATIVE RAW disks is calculated from the
number of fibs and number of disks or a max of 256. This causes poor disk
IO performance.

The fix is to set default qd based on the type of disks
(SATA -32 and SAS -64)
