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.

2016-07-15hpsa: correct skipping masked peripheralsDon Brace
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.

2015-11-09scsi: use host wide tags by defaultChristoph Hellwig
This patch changes the !blk-mq path to the same defaults as the blk-mq I/O path by always enabling block tagging, and always using host wide tags. We've had blk-mq available for a few releases so bugs with this mode should have been ironed out, and this ensures we get better coverage of over tagging setup over different configs.
