Pull SCSI updates from James Bottomley: "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 driver 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 wonder. There's also a "myrb" driver, where the 'b' stands for 'block'.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
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.

2018-06-05scsi: hpsa: disable device during shutdownSinan Kaya
'Commit cc27b735ad3a ("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 84676c1f21e8 ("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.

2017-10-25scsi: hpsa: update discovery pollingBader Ali Saleh
Correct a corner case where newly created volumes are not detected automatically on an external RAID controller that has no configured volumes during initial device discovery. 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.
