6f4e626fb0 scsi: ata: Use unsigned int for cmd's type in ioctls in scsi_host_template
Clang warns several times in the scsi subsystem (trimmed for brevity):

drivers/scsi/hpsa.c:6209:7: warning: overflow converting case value to
switch condition type (2147762695 to 18446744071562347015) [-Wswitch]
        case CCISS_GETBUSTYPES:
             ^
drivers/scsi/hpsa.c:6208:7: warning: overflow converting case value to
switch condition type (2147762694 to 18446744071562347014) [-Wswitch]
        case CCISS_GETHEARTBEAT:
             ^

The root cause is that the _IOC macro can generate really large numbers,
which don't fit into type 'int', which is used for the cmd parameter in
the ioctls in scsi_host_template. My research into how GCC and Clang are
handling this at a low level didn't prove fruitful. However, looking at
the rest of the kernel tree, all ioctls use an 'unsigned int' for the
cmd parameter, which will fit all of the _IOC values in the scsi/ata
subsystems.

Make that change because none of the ioctls expect a negative value for
any command, it brings the ioctls inline with the reset of the kernel,
and it removes ambiguity, which is never good when dealing with compilers.

2a3d4eb8e2 scsi: flip the default on use_clustering
Most SCSI drivers want to enable "clustering", that is merging of
segments so that they might span more than a single page.  Remove the
ENABLE_CLUSTERING define, and require drivers to explicitly set
DISABLE_CLUSTERING to disable this feature.

d49f8a52b1 SCSI misc on 20181024
This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380,
 qla2xxx, lpfc, libsas, hisi_sas.  In addition there's a set of mostly
 small updates to the target subsystem a set of conversions to the
 generic DMA API, which do have some potential for issues in the older
 drivers but we'll handle those as case by case fixes. A new myrs for
 the DAC960/mylex raid controllers to replace the block based DAC960
 which is also being removed by Jens in this merge window. Plus the
 usual slew of trivial changes.

[ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even

6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

0d98ba8d70 scsi: hpsa: disable device during shutdown
'Commit cc27b735ad ("PCI/portdrv: Turn off PCIe services during
shutdown")' has been added to kernel to shutdown pending PCIe port service
interrupts during reboot so that a newly started kexec kernel wouldn't
observe pending interrupts.

pcie_port_device_remove() is disabling the root port and switches by
calling pci_disable_device() after all PCIe service drivers are shutdown.

This has been found to cause crashes on HP DL360 Gen9 machines during
reboot due to hpsa driver not clearing the bus master bit during the
shutdown procedure by calling pci_disable_device().

Disable device as part of the shutdown sequence.

Since commit 84676c1f21 ("genirq/affinity: assign vectors to all
possible CPUs") we could end up with an MSI-X vector that did not have
any online CPUs mapped. This would lead to I/O hangs since there was no
CPU to receive the completion.

Retrieve IRQ affinity information using pci_irq_get_affinity() and use
this mapping to choose a reply queue.

Here is the set of "big" driver core patches for 4.16-rc1.
 
 The majority of the work here is in the firmware subsystem, with reworks
 to try to attempt to make the code easier to handle in the long run, but
 no functional change.  There's also some tree-wide sysfs attribute
 fixups with lots of acks from the various subsystem maintainers, as well
 as a handful of other normal fixes and changes.
 
 And finally, some license cleanups for the driver core and sysfs code.
 
 All have been in linux-next for a while with no reported issues.

Correct a corner case where newly created volumes are not detected
automatically on an external RAID controller that has no configured

The fix is to set the discovery_polling flag when an external RAID
controller is detected. This causes a device rescan every 20-30 seconds,
so that newly created volumes will be detected automatically.

symlinks remain under /sys/class/sas_phy. Fix this by
calling sas_phy_delete() rather than sas_phy_free (which,
according to comments, should not be called for PHYs that
have been set up successfully, anyway).

dfb2e6f46b scsi: hpsa: destroy sas transport properties before scsi_host
This patch cleans up a lot of warnings when unloading the driver.

A current example of the stack trace starts with:
    [  142.570715] sysfs group 'power' not found for kobject 'port-5:0'
There can be hundreds of these messages during a driver unload.

I am resubmitting this patch on behalf of Martin Wilck with his
permission.

His original patch can be found here:
https://www.spinics.net/lists/linux-scsi/msg102085.html

This patch did not help until Hannes's
commit 9441284fbc39 ("scsi-fixup-kernel-warning-during-rmmod")
was applied to the kernel.

---------------------------
Original patch description:
---------------------------

Unloading the hpsa driver causes warnings

[ 1063.793652] WARNING: CPU: 1 PID: 4850 at ../fs/sysfs/group.c:237 device_del+0x54/0x240()
[ 1063.793659] sysfs group ffffffff81cf21a0 not found for kobject 'port-2:0'

with two different stacks:
1)
[ 1063.793774]  [<ffffffff81448af4>] device_del+0x54/0x240
[ 1063.793780]  [<ffffffff8145178a>] transport_remove_classdev+0x4a/0x60

[ 1063.793819]  [<ffffffffa036ebcc>] hpsa_free_sas_port+0x3c/0x70 [hpsa]

2)
[ 1063.797103]  [<ffffffff81448af4>] device_del+0x54/0x240
[ 1063.797118]  [<ffffffffa0105d4e>] sas_port_delete+0x12e/0x160 [scsi_transport_sas]
[ 1063.797134]  [<ffffffffa036ebcc>] hpsa_free_sas_port+0x3c/0x70 [hpsa]

This is caused by the fact that host device hostX is deleted before the
SAS transport devices hostX/port-a:b.

This patch fixes this by reverting the order of device deletions.

The hpsa firmware will bypass the cache for any request larger than 1MB,
so we should cap the request size to avoid any performance degradation
in kernels later than v4.3

This degradation is caused from d2be537c3b,
which changed max_sectors_kb to 1280k, but the hardware is able to work
fine with it, so the true fix should be from hpsa driver.

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.

 an assortment of minor fixes, mostly in error legs or other not very

 replacement for the old pci_msix_.. calls; this effectively makes IRQ
 mapping generic for the drivers and allows blk_mq to use the

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.

c3390df475 hpsa: check for a null phys_disk pointer in ioaccel2 path
An oops can occur when submitting ioaccel2 commands when the phys_disk
pointer is NULL in hpsa_scsi_ioaccel_raid_map.  Happens when there are
configuration changes during I/O operations.

If the phys_disk pointer is NULL, send the command down the RAID path.
