2016-11-22scsi: mpt3sas: Unblock device after controller resetSuganath Prabu S
While issuing any ATA passthrough command to firmware the driver will block the device. But it will unblock the device only if the I/O completes through the ISR path. If a controller reset occurs before command completion the device will remain in blocked state. Make sure we unblock the device following a controller reset if an ATA passthrough command was queued.

Older controllers use SCSI target id '0' for the first internal disk.

2016-11-14scsi: qla2xxx: do not abort all commands in the adapter during EEH recoveryMauricio Faria de Oliveira
The previous commit 1535aa75a3d8 ("qla2xxx: fix invalid DMA access after command aborts in PCI device remove") introduced a regression during an EEH recovery, since the change to the qla2x00_abort_all_cmds() function calls qla2xxx_eh_abort(), which verifies the EEH recovery condition but handles it heavy-handed. (commit a465537ad1a4 "qla2xxx: Disable the adapter and skip error recovery in case of register disconnect.") This problem warrants a more general/optimistic solution right into qla2xxx_eh_abort() (eg in case a real command abort arrives during EEH recovery, or if it takes long enough to trigger command aborts); but it's still worth to add a check to ensure the code added by the previous commit is correct and contained within its owner function. This commit just adds a 'if (!ha->flags.eeh_busy)' check around it. (ahem; a trivial fix for this -rc series; sorry for this oversight.) With it applied, both PCI device remove and EEH recovery works fine.

2016-11-14sd_zbc: Force use of READ16/WRITE16Damien Le Moal
Normally, sd_read_capacity sets sdp->use_16_for_rw to 1 based on the disk capacity so that READ16/WRITE16 are used for large drives. However, for a zoned disk with RC_BASIS set to 0, the capacity reported through READ_CAPACITY may be very small, leading to use_16_for_rw not being set and READ10/WRITE10 commands being used, even after the actual zoned disk capacity is corrected in sd_zbc_read_zones. This causes LBA offset overflow for accesses beyond 2TB. As the ZBC standard makes it mandatory for ZBC drives to support the READ16/WRITE16 commands anyway, make sure that use_16_for_rw is set.

2016-11-12scsi: mpt3sas: Fix secure erase premature terminationAndrey Grodzovsky
This is a work around for a bug with LSI Fusion MPT SAS2 when perfoming secure erase. Due to the very long time the operation takes, commands issued during the erase will time out and will trigger execution of the abort hook. Even though the abort hook is called for the specific command which timed out, this leads to entire device halt (scsi_state terminated) and premature termination of the secure erase. Set device state to busy while ATA passthrough commands are in progress.

2016-11-12scsi: hpsa: use pci_alloc_irq_vectors and automatic irq affinityChristoph Hellwig
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.
