Commit 1f02beff22 ("scsi: pm80xx: Remove global lock from outbound queue
processing") introduced a lock per outbound queue. Prior to that change the
driver was using a global lock for all outbound queues.
While processing the I/O responses and events the driver takes the outbound
queue spinlock and is supposed to release it in pm8001_ccb_task_free_done()
before calling command done(). Since the older code was using a global
lock, pm8001_ccb_task_free_done() was releasing the global spin lock. The
change that split the lock per outbound queue did not consider this and
pm8001_ccb_task_free_done() was still releasing the global lock.

During phyup event, the firmware provides the phy_id and port_id and driver
is supposed to use these during device handle registration. Previously the
driver was using the port id value from libsas during device handle
registration. Since id can be different from the one assigned by firmware,
this can lead to wrong device registration and drives not showing up.
Use firmware assigned port id during device registration.

Offlining a SATA device connected to a hisi SAS controller and then

...
[2:0:1:255] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdjb
After a REPORT LUN command issued to the offline device fails, the SCSI
midlayer tries to do a sequential scan of all devices whose LUN number is
not 0. However, SATA does not support LUN numbers at all.
Introduce a generic sas_slave_alloc() handler which will return -ENXIO for
SATA devices if the requested LUN number is larger than 0 and make libsas
drivers use this function as their .slave_alloc callback.

When driver is loaded after rmmod some drives are not showing up during
discovery.
SATA drives are directly attached to the controller connected phys. During
device discovery, the IDENTIFY command (qc timeout (cmd 0xec)) is timing out
during revalidation. This will trigger abort from host side and controller
successfully aborts the command and returns success. Post this successful
abort response ATA library decides to mark the disk as NODEV.
To overcome this, inside pm8001_scan_start() after phy_start() call, add get
start response and wait for few milliseconds to trigger next phy start.
This millisecond delay will give sufficient time for the controller state
machine to accept next phy start.

The for-loop iterates with a u8 loop counter i and compares this with the
loop upper limit of pm8001_ha->max_q_num which is a u32 type. There is a
potential infinite loop if pm8001_ha->max_q_num is larger than the u8 loop
counter. Fix this by making the loop counter the same type as
pm8001_ha->max_q_num.
[mkp: this is purely theoretical, max_q_num is currently limited to 64]

mpi_uninit_check() is not being called in an atomic context. The only
caller of mpi_uninit_check() is pm80xx_chip_soft_rst().
Callers of pm80xx_chip_soft_rst():
- pm8001_ioctl_soft_reset()
- pm8001_pci_probe()
- pm8001_pci_remove()
- pm8001_pci_suspend()
- pm8001_pci_resume()

The mpi_uninit_check() takes longer for inbound doorbell register to be
cleared. Increase the timeout substantially so that the driver does not
fail to load.
Previously, the inbound doorbell wait time was mistakenly increased in the
mpi_init_check() instead of mpi_uninit_check(). It is okay to leave the
mpi_init_check() wait time as-is as these are timeout values and if there
is a failure, waiting longer is not an issue.

On some configurations, gcc warns about overlapping source and destination
arguments to snprintf:
drivers/scsi/pm8001/pm8001_init.c: In function 'pm8001_request_msix':
drivers/scsi/pm8001/pm8001_init.c:977:3: error: 'snprintf' argument 4 may overlap destination object 'pm8001_ha' [-Werror=restrict]
977 | snprintf(drvname, len, "%s-%d", pm8001_ha->name, i);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

962 | static u32 pm8001_request_msix(struct pm8001_hba_info *pm8001_ha)
| ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~
I first assumed this was a gcc bug, as that should not happen, but a
reduced test case makes it clear that this happens when the loop counter is
not bounded by the array size.
Help the compiler out by adding an explicit limit here to make the code
slightly more robust and avoid the warning.

libsas event notifiers required an extension where gfp_t flags must be
explicitly passed. For bisectability, a temporary _gfp() variant of such
functions were added. All call sites then got converted use the _gfp()
variants and explicitly pass GFP context. Having no callers left, the
original libsas notifiers were then modified to accept gfp_t flags by
default.
Switch back to the original libas API, while still passing GFP context.
The libsas _gfp() variants will be removed afterwards.
