[SCSI] qla4xxx: Reduce rom-lock contention during reset recovery.
Issue:
Driver holds rom-lock for too long during reset recovery.
During adapter reset testing, it was found that the driver
holds the rom-lock for too long, because of which other
drivers fail to acquire the rom-lock, leading to reset
failures.
The primary cause is, in the bootstrap code, while
holding the rom-lock, the driver checks if the peg is
halted, causing a 2 second contention.
Fix:
When a reset recovery starts, the driver deduces the cause, and
sets appropriate flags in watchdog & recover_adapter routines.
This flag should be used to determine if bootstrap is invoked
from probe or reset context, reducing the rom-lock footprint of
the drivers.

Allow driver to schedule a rescan whenever a request fails on the ioaccel2 path.
This eliminates the possibility of driver getting stuck in non-ioaccel mode.
IOaccel mode (HP SSD Smart Path) is disabled by driver upon error detection.
Driver relied on idea that request would be retried through normal path, and a
subsequent error would occur on that path, and be processed by controller
firmware. As part of that process, controller disables ioaccel mode and later
reinstates it, signalling driver to change modes.
In some error cases, the error will not duplicate on the standard path,
so the driver could get stuck in non-ioaccel mode.
To avoid that, we allow driver to request a rescan during the next run of the

[SCSI] hpsa: poll controller to detect device change event
For shared SAS configurations, hosts need to poll Smart Arrays
periodically in order to be able to detect configuration changes
such as logical drives being added or removed from remote hosts.
A register on the controller indicates when such events have
occurred, and the driver polls the register via a workqueue
and kicks off a rescan of devices if such an event is detected.
Additionally, changes to logical drive raid offload eligibility
are autodetected in this way.

254f796b9f22b1944c64caabc356a56caaa2facd updated

older controllers would provide only 4.
This was causing MSI-X registration to drop down to INTx

to stall during boot.
This patch fixes up the MSI-X registration to re-issue

res 51/40:01:00:00:00/00:00:00:00:00/e0 Emask 0x9 (media error)

dev->sata_dev.fis[3] = 0x04; /* status err */

libsas sometimes short circuits timeouts to force commands into error

It's also redundant in the case of a true timeout as libata eh will
