commit 8b834bff1b upstream.
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.

commit 0d98ba8d70 upstream.
'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.

[ Upstream commit dfb2e6f46b ]
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()

[ 1063.797134] [<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.

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).

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.

Older SmartArray controllers (eg SmartArray 64xx) do not support the
extended REPORT PHYS command, so fallback to use the legacy version
here.

Passing one instead of 8 or 16 arguments reduces the size of the
generated code somewhat:
add/remove: 2/3 grow/shrink: 1/4 up/down: 1772/-2137 (-365)
There's one more candidate, unique_id_show, but that uses %02X, and I'm
not sure it would be ok to start using lowercase there, so I've left it
alone for now.

Add a sysfs attribute 'ctlr_num' holding the current HPSA controller
number. This is required to construct compability 'cciss' links.

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.

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.

It's not necessary to cast the result of kmalloc, since void pointers
are promoted to any other type. This also fixes following coccinelle
warning:
casting value returned by memory allocation function to (BIG_IOCTL_Command_struct *) is useless.
