Pull blk-mq irq/cpu mapping updates from Jens Axboe:
"This is the block-irq topic branch for 4.9-rc. It's mostly from
Christoph, and it allows drivers to specify their own mappings, and
more importantly, to share the blk-mq mappings with the IRQ affinity
mappings. It's a good step towards making this work better out of the
box"

Pull SCSI updates from James Bottomley:
"This update includes the usual round of major driver updates (hpsa,
be2iscsi, hisi_sas, zfcp, cxlflash). There's a new incarnation of hpsa
called smartpqi for which a driver is added, there's some cleanup work
of the ibm vscsi target and updates to libfc, plus a whole host of
minor fixes and updates and finally the removal of several ISA drivers
which seem not to have been used for years"

Pull CPU hotplug updates from Thomas Gleixner:
"Yet another batch of cpu hotplug core updates and conversions:
- Provide core infrastructure for multi instance drivers so the
drivers do not have to keep custom lists.
- Convert custom lists to the new infrastructure. The block-mq custom
list conversion comes through the block tree and makes the diffstat
tip over to more lines removed than added.
- Handle unbalanced hotplug enable/disable calls more gracefully.
- Remove the obsolete CPU_STARTING/DYING notifier support.
- Convert another batch of notifier users.
The relayfs changes which conflicted with the conversion have been
shipped to me by Andrew.
The remaining lot is targeted for 4.10 so that we finally can remove

Pull SCSI fix from James Bottomley:
"One final fix before 4.8.
There was a memory leak triggered by turning scsi mq off due to the
fact that we assume on host release that the already running hosts
weren't mq based because that's the state of the global flag (even
though they were).
Fix it by tracking this on a per host host basis"

When any UFS host controller receives a TM(Task Management) response
from a UFS device, UFS driver has been recognize like receiving a
message of "Task Management Function Complete"(00h) in all cases, so
far. That means there is no pending task for a tag of the TM request
sent before in the UFS device. That's because the byte offset 6 in TM
response which has been used to get a TM service response so far
represents just whether or not a TM transmission passes.
Regarding UFS spec, the correct byte offset to get TM service response
is 15, not 6.
I tested that UFS driver responds properly for the TM response from a
UFS device with an reference board with exynos8890, as follow: No
pending task -> Task Management Function Complete (00h) Pending task ->
Task Management Function Succeeded (08h)

If a VFC port gets unmapped in the VIOS, it may not respond with a CRQ
init complete following H_REG_CRQ. If this occurs, we can end up having
called scsi_block_requests and not a resulting unblock until the init
complete happens, which may never occur, and we end up hanging I/O
requests. This patch ensures the host action stay set to
IBMVFC_HOST_ACTION_TGT_DEL so we move all rports into devloss state and
unblock unless we receive an init complete.

Install the callbacks via the state machine. It uses the multi instance
infrastructure of the hotplug code to handle each interface.
virtscsi_set_affinity() is removed from virtscsi_init() because
virtscsi_cpu_notif_add() (the function which registers the instance) is invoked
right after it and the cpuhp_state_add_instance() functions invokes the startup
callback on all online CPUs.
The same thing can not be applied virtscsi_cpu_notif_remove() because
virtscsi_remove_vqs() invokes virtscsi_set_affinity() with affinity = false as
argument but the old CPU_DEAD state invoked the function with affinity = true
(which does not match the DEAD callback).

We get a few warnings when building kernel with W=1:
drivers/scsi/megaraid/megaraid_sas_fusion.c:281:1: warning: no previous prototype for 'megasas_free_cmds_fusion' [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_fusion.c:714:1: warning: no previous prototype for 'megasas_ioc_init_fusion' [-Wmissing-prototypes]
....
In fact, these functions are declared in
drivers/scsi/megaraid/megaraid_sas_base.c, but should be declared in a
header file, thus can be recognized in other file.
So this patch adds the declarations into
drivers/scsi/megaraid/megaraid_sas_fusion.h.

Whenever multiple HRRQs are enabled, which is the default setting now,
we end up seeing the following message logged prior to initialization of
each HRRQ:
Starting IOA initialization sequence
This results in 16 of these messages on most adapters, which serves
little purpose. Change to just log this once.

A 9084 error gets logged by the ipr adapter when adapter raw mode gets
enabled. A bunch of unformatted hex data also gets logged for this
error, which is of little use, so let's avoid logging it by default in
order to avoid the log getting polluted with useless data.

In the ioaccel path, the calculation of the starting LBA for
READ(6)/WRITE(6) SCSI commands does not take into account the most
significant 5 bits of the LBA: it only uses the least significant 16
bits of the starting LBA.

ULD's
Allocate resources dynamically to cxgb4's Upper layer driver's(ULD) like
cxgbit, iw_cxgb4 and cxgb4i. Allocate resources when they register with
cxgb4 driver and free them while unregistering. All the queues and the
interrupts for them will be allocated during ULD probe only and freed
during remove.

All drivers use the default, so provide an inline version of it. If we
ever need other queue mapping we can add an optional method back,
although supporting will also require major changes to the queue setup
code.
This provides better code generation, and better debugability as well.
