[PATCH 0/6] hisi_sas: DIX support, performance optimisation, and misc patches

This patchset introduces the following:
- DIX support for v3 hw

- Optimisation based on mapping CPUs to queues, much the same as other
SCSI drivers do today, without exposing > 1 queue to upper layer.

It is disabled by default and marked as experimental, due to ongoing
discussion here:
https://marc.info/?l=linux-scsi&m=154876335707751&w=2

In addition, hopefully we can eventually expose > 1 queue to upper
layer and remove the reply_map, if performance issue discussed here has
a positive outcome:
https://marc.info/?l=linux-scsi&m=154874776701343&w=2

- And some other minor tidying and a driver debugfs feature

This series is based on Martin's 5.1 queue +
"scsi: hisi_sas: Set protection parameters prior to adding SCSI host"

John Garry (2):
scsi: hisi_sas: Issue internal abort on all relevant queues
scsi: hisi_sas: Do some more tidy-up

Luo Jiaxing (1):
scsi: hisi_sas: Add manual trigger for debugfs dump

Xiang Chen (3):
scsi: hisi_sas: Add support for DIX feature for v3 hw
scsi: hisi_sas: change queue depth from 512 to 4096
scsi: hisi_sas: Use pci_irq_get_affinity() for v3 hw as experimental
