System crash due to use after free.
Current code allows terminate_rport_io to exit before making
sure all IOs has returned. For FCP-2 device, IO's can hang
on in HW because driver has not tear down the session in FW at
first sign of cable pull. When dev_loss_tmo timer pops,
terminate_rport_io is called and upper layer is about to
free various resources. Terminate_rport_io trigger qla to do
the final cleanup, but the cleanup might not be fast enough where it
leave qla still holding on to the same resource.
Wait for IO's to return to upper layer before resources are freed.

Commit b6faaaf796 ("scsi: qla2xxx: Serialize mailbox request") serialized
mailbox requests from userspace using the 'optrom' mutex. However, in the
case of DCBX TLV data, if the memory for it is already allocated, then the
mailbox request ends up not being serialized because it is done without
holding the 'optrom' mutex.

Some FC adapters from Marvell offer the ability to encrypt data in flight
(EDIF). This feature requires an application to act as an authenticator.
During runtime, driver and authentication application need to stay in sync
in terms of: Session being down|up, arrival of new authentication
message (AUTH ELS) and SADB update completion.
These events are queued up as doorbell to the authentication
application. Application would read this doorbell on regular basis to stay
up to date. Each SCSI host would have a separate doorbell queue.
The doorbell interface can daisy chain a list of events for each read. Each
event contains an event code + hint to help application steer the next
course of action.

Normally, the MPI firmware is reset when an MPI dump is collected. If an
unsaved MPI dump exists in the driver, though, an alternate mechanism is
used. This mechanism, which was not fully correct, is not recommended and
instead an MPI dump template walk is suggested to perform the MPI reset.
To allow for the MPI dump template walk, extra space is reserved in the MPI
dump buffer which gets used only when there is already an MPI dump in
place.

Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular
firmware dump is also taken and then chip reset. This is disruptive to IOs
and not required. Make the firmware dump collection, followed by chip
reset, optional (not done by default).
Firmware dump buffer and MPI dump buffer are independent of each
other with this change and each can have dump that was taken at two
different times for two different issues. The MPI dump is saved in a
separate buffer and is retrieved differently from firmware dump.
To collect full dump on MPI failure AEN, a module parameter is
introduced:
ql2xfulldump_on_mpifail (default: 0)

First, to allow driver to gain LED control, do this:
# echo 1 > /sys/class/scsi_host/host#/beacon
Then, to display config words for all three LEDs do this:
# cat /sys/class/scsi_host/host#/beacon_config
To set config words for all three LEDs do this:
# echo 3 xxxx yyyy zzzz > /sys/class/scsi_host/host#/beacon_config
Or, to set config word for a specific single LED n do this:
# echo n xxxx > /sys/class/scsi_host/host#/beacon_config
where n is the LED number (0, 1, 2)
Finally, to restore LED control back to firmware, do this:
# echo 0 > /sys/class/scsi_host/host#/beacon

For new adapters with multiple flash regions to write to, current code
allows FW & Boot regions to be written, while other regions are blocked via
sysfs. The fix is to block all flash read/write through sysfs interface.
Fixes: e81d1bcbde ("scsi: qla2xxx: Further limit FLASH region write access from SysFS")

For MPI heartbeat stop Async Event, this patch would capture MPI FW dump
and chip reset. FW will tell which function to capture FW dump for.

This is mostly update of the usual drivers: qla2xxx, ufs, smartpqi,
lpfc, hisi_sas, qedf, mpt3sas; plus a whole load of minor updates.
The only core change this time around is the addition of request
batching for virtio. Since batching requires an additional flag to
use, it should be invisible to the rest of the drivers.

If HBA initialization fails unexpectedly (exiting via probe_failed:), we
may fail to free vha->gnl.l. So that we don't attempt to double free, set
this pointer to NULL after a free and check for NULL at probe_failed: so we
know whether or not to call dma_free_coherent.
