No functional change. Code optimization.
One can simply check 'target_busy' or 'device_busy' when figuring out if
there are outstanding commands; no need to painstakingly count them by
hand.

1. In IO path, setting of "ATA command pending" flag early before device
removal, invalid device handle etc., checks causes any new commands
to be always returned with SAM_STAT_BUSY and when the driver removes
the drive the SML issues SYNC Cache command and that command is
always returned with SAM_STAT_BUSY and thus making SYNC Cache command
to requeued.
2. If the driver gets an ATA PT command for a SATA drive then the driver
set "ATA command pending" flag in device specific data structure not
to allow any further commands until the ATA PT command is completed.
However, after setting the flag if the driver decides to return the
command back to upper layers without actually issuing to the firmware
(i.e., returns from qcmd failure return paths) then the corresponding
flag is not cleared and this prevents the driver from sending any new
commands to the drive.
This patch fixes above two issues by setting of "ATA command pending"
flag after checking for whether device deleted, invalid device handle,
device busy with task management. And by setting "ATA command pending"
flag to false in all of the qcmd failure return paths after setting the
flag.

* The hardware translation of IEEE SGL to NVMe PRPs has limitations
and if a command cannot be translated by hardware then it will go to
firmware and the firmware needs to translate it. This will have a
performance impact. To avoid that, the driver proactively checks
whether the translation will be done in hardware or not. If not, then
driver translates.

Commit <f2e767bb5d6e> ("mpt3sas: Force request partial completion
alignment") was not considering the case of commands not operating on
logical block size units (e.g. REQ_OP_ZONE_REPORT and its 64B aligned
partial replies). In this case, forcing alignment of resid to the device
logical block size can break the command result, e.g. in the case of
REQ_OP_ZONE_REPORT, the exact number of zone reported by the device.
Move the partial completion alignement check of mpt3sas to a generic
implementation in sd_done(). The check is added within the default
section of the initial req_op() switch case so that the report and reset
zone commands are ignored. In addition, as sd_done() is not called for
passthrough requests, resid corrections are not done as intended by the
initial mpt3sas patch.

The firmware or device, possibly under a heavy I/O load, can return on a
partial unaligned boundary. Scsi-ml expects these requests to be
completed on an alignment boundary. Scsi-ml blindly requeues the I/O
without checking the alignment boundary of the I/O request for the
remaining bytes. This leads to errors, since devices cannot perform
non-aligned read/write operations.
This patch fixes the issue in the driver. It aligns unaligned
completions of FS requests, by truncating them to the nearest alignment
boundary.

Driver processes the event MPI26_EVENT_ACTIVE_CABLE_DEGRADED when a
cable is present and is running at a degraded speed (below the SAS3 12
Gb/s rate). Prints added to inform the user that the cable is not
running at optimal speed.

mpt3sas has a firmware failure where it can only handle one pass through
ATA command at a time. If another comes in, contrary to the SAT
standard, it will hang until the first one completes (causing long
commands like secure erase to timeout). The original fix was to block
the device when an ATA command came in, but this caused a regression
with

scsi: srp_transport: Move queuecommand() wait code to SCSI core
So fix the original fix of the secure erase timeout by properly
returning SAM_STAT_BUSY like the SAT recommends. The original patch
also had a concurrency problem since scsih_qcmd is lockless at that
point (this is fixed by using atomic bitops to set and test the flag).

This patch adds support for request iopriority handling in the mpt3sas
layer. This works only when a ATA device is behind the SATL. The ATA
device also has to indicate that it supports command priorities in the
identify information that is pulled from the SATL.

This update includes the usual round of major driver updates (ncr5380,
lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas). There's also
an assortment of minor fixes, mostly in error legs or other not very
user visible stuff. The major change is the pci_alloc_irq_vectors
replacement for the old pci_msix_.. calls; this effectively makes IRQ
mapping generic for the drivers and allows blk_mq to use the
information.

While issuing any ATA passthrough command to firmware the driver will
block the device. But it will unblock the device only if the I/O
completes through the ISR path. If a controller reset occurs before
command completion the device will remain in blocked state.
Make sure we unblock the device following a controller reset if an ATA
passthrough command was queued.

This is a work around for a bug with LSI Fusion MPT SAS2 when perfoming
secure erase. Due to the very long time the operation takes, commands
issued during the erase will time out and will trigger execution of the
abort hook. Even though the abort hook is called for the specific
command which timed out, this leads to entire device halt
(scsi_state terminated) and premature termination of the secure erase.
Set device state to busy while ATA passthrough commands are in progress.

An UNMAP command on a PI formatted device will leave the Logical Block
Application Tag and Logical Block Reference Tag as all F's (for those LBAs
that are unmapped). To avoid IO errors if those LBAs are subsequently read
before they are written with valid tag fields, the MPI SCSI IO requests
need to set the EEDPFlags element EEDP Escape Mode field, Bits [7:6]
appropriately. A value of 2 should be set to disable all PI checks if the
Logical Block Application Tag is 0xFFFF for PI types 1 and 2. A value
of 3 should be set to disable all PI checks if the Logical Block
Application Tag is 0xFFFF and the Logical Block Reference Tag is
0xFFFFFFFF for PI type 3.
