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.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

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.

The fix is to set the discovery_polling flag when an external RAID

so that newly created volumes will be detected automatically.

55ca38b425 scsi: hpsa: cleanup sas_phy structures in sysfs when unloading 
I am resubmitting this patch on behalf of Martin Wilck with his
permission.

The original patch can be found here:
https://www.spinics.net/lists/linux-scsi/msg102083.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 from Martin:
--------------------------------------

When the hpsa module is unloaded using rmmod, dangling
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).

Unloading the hpsa driver causes warnings

[ 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.

 - 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

 - 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.
