b63c64ac5a scsi: hpsa: send ioaccel requests with 0 length down raid path
- Block I/O requests with 0 length transfers which go down the ioaccel
  path. This causes lockup issues down in the basecode.
- These issues have been fixed, but there are customers who are
  experiencing the issues when running older firmware.

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.

7630b3a599 scsi: hpsa: use bus '3' for legacy HBA devices
Older controllers use SCSI target id '0' for the first internal disk. As
the controllers are now placed on the same bus as the internal disks
this leads to a clash with the SCSI target id of controller.  This patch
checks the SCSI revision, and moves older controller to bus '3' to be
compatible with older releases and avoid this problem.

bc2bb1543e scsi: hpsa: use pci_alloc_irq_vectors and automatic irq affinity
This patch converts over hpsa to use the pci_alloc_irq_vectors including
the PCI_IRQ_AFFINITY flag that automatically assigns spread out irq
affinity to the I/O queues.

It also cleans up the per-ctrl interrupt state due to the use of the
pci_irq_vector and pci_free_irq_vectors helpers that don't need to know
the exact irq type.  Additionally it changes a little oddity in the
existing code that was using different array indixes into the per-vector
arrays depending on whether a controller is using a single INTx or
single MSI irq.

64ce60cab2 hpsa: correct skipping masked peripherals
The SA controller spins down RAID drive spares.

A REGNEWD event causes an inquiry to be sent to all physical
drives. This causes the SA controller to spin up the spare.

The controller suspends all I/O to a logical volume until
the spare is spun up. The spin-up can take over 50 seconds.

This can result in one or both of the following:
 - SML sends down aborts and resets to the logical volume
   and can cause the logical volume to be off-lined.
 - a negative impact on the logical volume's I/O performance
   each time a REGNEWD is triggered.

The original code places a check for TYPE_ZBC right after the check for
TYPE_DISK. Logically, if the first if statement sees a device of a
TYPE_DISK and moves on to the second statement checking if not TYPE_ZBC,
it will always hit the continue.

The driver was calling scsi_scan_host before enabling interrupts.

This has gone unnoticed except for customers running in intx mode.
Calling scsi_scan_host before interrupts are enabled causes
"irq XX: nobody cared" messages and the driver to hang.

This patch enables interrupts before the call to scsi_scan_host.
