A recent change removed the dependency on BLK_DEV_NVME, which implies
the dependency on PCI and BLOCK. We don't need CONFIG_PCI, but without
CONFIG_BLOCK we get tons of build errors, e.g.
In file included from drivers/nvme/host/core.c:16:0:
linux/blk-mq.h:182:33: error: 'struct gendisk' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
drivers/nvme/host/core.c: In function 'nvme_setup_rw':
drivers/nvme/host/core.c:295:21: error: implicit declaration of function 'rq_data_dir' [-Werror=implicit-function-declaration]
drivers/nvme/host/nvme.h: In function 'nvme_map_len':
drivers/nvme/host/nvme.h:217:6: error: implicit declaration of function 'req_op' [-Werror=implicit-function-declaration]

drivers/nvme/host/scsi.c:768:85: error: implicit declaration of function 'queue_max_hw_sectors' [-Werror=implicit-function-declaration]
This adds back the specific CONFIG_BLOCK dependency to avoid broken
configurations.

If there is an error on req->mr, req->mr is set to null, however
the following statement sets req->mr->need_inval causing a null
pointer dereference. Fix this by bailing out to label 'out' to
immediately return and hence skip over the offending null pointer
dereference.

Change nvme-rdma to use the IB Client API to detect device removal.
This has the wonderful benefit of being able to blow away all the
ib/rdma_cm resources for the device being removed. No craziness about
not destroying the cm_id handling the event. No deadlocks due to broken
iw_cm/rdma_cm/iwarp dependencies. And no need to have a bound cm_id
around during controller recovery/reconnect to catch device removal
events.
We don't use the device_add aspect of the ib_client service since we only
want to create resources for an IB device if we have a target utilizing
that device.

When we get a surprise disconnect from the target we queue a periodic
reconnect (which is the sane thing to do...).
We only move the queues out of CONNECTED when we retry to reconnect (after
10 seconds in the default case) but we stop the blk queues immediately
so we are not bothered with traffic from now on. If delete() is kicking
off in this period the queues are still in CONNECTED state.
Part of the delete sequence is trying to issue ctrl shutdown if the
admin queue is CONNECTED (which it is!). This request is issued but
stuck in blk-mq waiting for the queues to start again. This might be
the one preventing us from forward progress...
The patch separates the queue flags to CONNECTED and DELETING. Now we
will move out of CONNECTED as soon as error recovery kicks in (before
stopping the queues) and DELETING is on when we start the queue deletion.

When testing Lubbock, it was noticed that the sa1111 pcmcia driver bound
but was not functional due to no sockets being registered. This is
because the return code from the lowlevel board initialisation was not

A decent point was raised about minimising the use of a local variable that
we 'could' do without. I've chosen consistency over the possibility of
reducing the local variable count by 1. Thinking that it's more important
for the code to be grouped and authoured in a similar manner/style for
greater maintainability/readability.

Commit aa71987472a9 ("nvme: fabrics drivers don't need the nvme-pci

depend on the block layer (which used to be an implicit dependency
through BLK_DEV_NVME).
Otherwise you get various errors from the kbuild test robot random
config testing when that happens to hit a configuration with BLOCK

Due to a mistake in the hardware manual, the FWSLC and POST1-4 registers
were not documented and left out of the driver for RZ/A making the CAM
feature non-operational.
Additionally, when the offset values for POST1-4 are left blank, the driver
attempts to set them using an offset of 0xFFFF which can cause a memory
corruption or panic.
This patch fixes the panic and properly enables CAM.

Pull libnvdimm fixes from Dan Williams:
"nvdimm fixes for v4.8, two of them are tagged for -stable:
- Fix devm_memremap_pages() to use track_pfn_insert(). Otherwise,
DAX pmd mappings end up with an uncached pgprot, and unusable
performance for the device-dax interface. The device-dax interface
appeared in 4.7 so this is tagged for -stable.
- Fix a couple VM_BUG_ON() checks in the show_smaps() path to
understand DAX pmd entries. This fix is tagged for -stable.
- Fix a mis-merge of the nfit machine-check handler to flip the
polarity of an if() to match the final version of the patch that
Vishal sent for 4.8-rc1. Without this the nfit machine check
handler never detects / inserts new 'badblocks' entries which
applications use to identify lost portions of files.
- For test purposes, fix the nvdimm_clear_poison() path to operate on
legacy / simulated nvdimm memory ranges. Without this fix a test
can set badblocks, but never clear them on these ranges.
- Fix the range checking done by dax_dev_pmd_fault(). This is not
tagged for -stable since this problem is mitigated by specifying
aligned resources at device-dax setup time.
These patches have appeared in a next release over the past week. The
recent rebase you can see in the timestamps was to drop an invalid fix
as identified by the updated device-dax unit tests [1]. The -mm
touches have an ack from Andrew"

Bad blocks can be injected via /sys/block/pmemN/badblocks. In a situation
where legacy pmem is being used or a pmem region created by using memmap
kernel parameter, the injected bad blocks are not cleared due to
nvdimm_clear_poison() failing from lack of ndctl function pointer. In
this case we need to just return as handled and allow the bad blocks to
be cleared rather than fail.

virtio_console uses a small DMA buffer for control requests. Move
that buffer into heap memory.
Doing virtio DMA on the stack is normally okay on non-DMA-API virtio
systems (which is currently most of them), but it breaks completely
if the stack is virtually mapped.
Tested by typing both directions using picocom aimed at /dev/hvc0.

commit 5f9d1fde7d54a5(raid5: fix memory leak of bio integrity data)
moves bio_reset to bio_endio. But it introduces a small race condition.
It does bio_reset after raid5_release_stripe, which could make the
stripe reusable and hence reuse the bio just before bio_reset. Moving
bio_reset before raid5_release_stripe is called should fix the race.

usb: fixes for v4.8-rc6
Unfortunately we have a bogus dwc3 patch leaked through the cracks and
got merged into Linus' HEAD. That patch ended up causing off-by-1 error
in our TRB accounting logic. Thankfully John Youn found out the problem
and we provided a revert to the bogus dwc3 patch in no time.
Apart from this off-by-1 error, we have two fixes to the Renesas drivers,
a small fix to our generic phy driver, a NULL pointer dereference fix for
f_eem and a build warning fix in dwc3.

Second set of IIO fixes for the 4.8 cycle.
We have a big rework of the kxsd9 driver queued up behind the fix below and
a fix for a recent fix that was marked for stable.
Hence this fix series is perhaps a little more urgent than average for IIO.
* core
- a fix for a fix in the last set. The recent fix for blocking ops when
! task running left a path (unlikely one) in which the function return
value was not set - so initialise it to 0.
- The IIO_TYPE_FRACTIONAL code previously didn't cope with negative
fractions. Turned out a fix for this was in Analog's tree but hadn't made
it upstream.
* bmc150
- reset chip at init time. At least one board out there ends up coming up
in an unstable state due to noise during power up. The reset does no
harm on other boards.
* kxsd9
- Fix a bug in the reported scaling due to failing to set the integer
part to 0.
* hid-sensors-pressure
- Output was in the wrong units to comply with the IIO ABI.
* tools
- iio_generic_buffer: Fix the trigger-less mode by ensuring we don't fault
out for having no trigger when we explicitly said we didn't want to have
one.

Problems with the signal integrity of the high speed USB data lines or
noise on reference ground lines can cause the i.MX6 USB controller to
violate USB specs and exhibit unexpected behavior.
It was observed that USBi_UI interrupts were triggered first and when
isr_setup_status_phase was called, ci->status was NULL, which lead to a
NULL pointer dereference kernel panic.
This patch fixes the kernel panic, emits a warning once and returns
-EPIPE to halt the device and let the host get stalled.
It also adds a comment to point people, who are experiencing this issue,
to their USB hardware design.
