Pull i2c updates from Wolfram Sang:
-I2C core now reports proper OF style module alias. I'd like to repeat
the note from the commit msg here (Thanks, Javier!):
NOTE: This patch may break out-of-tree drivers that were relying
on this behavior, and only had an I2C device ID table even
when the device was registered via OF.
There are no remaining drivers in mainline that do this, but
out-of-tree drivers have to be fixed and define a proper OF
device ID table to have module auto-loading working.
- new driver for the SynQuacer I2C controller
- major refactoring of the QUP driver
- the piix4 driver now uses request_muxed_region which should fix a
long standing resource conflict with the sp5100_tco watchdog
- a bunch of small core & driver improvements

"Notable changes:
- Support for 4PB user address space on 64-bit, opt-in via mmap().
- Removal of POWER4 support, which was accidentally broken in 2016
and no one noticed, and blocked use of some modern instructions.
- Workarounds so that the hypervisor can enable Transactional Memory
on Power9.
- A series to disable the DAWR (Data Address Watchpoint Register) on
Power9.
- More information displayed in the meltdown/spectre_v1/v2 sysfs
files.
- A vpermxor (Power8 Altivec) implementation for the raid6 Q
Syndrome.
- A big series to make the allocation of our pacas (per cpu area),
kernel page tables, and per-cpu stacks NUMA aware when using the
Radix MMU on Power9.
And as usual many fixes, reworks and cleanups.

After attempting to quickly retrieve known errors the kernel proceeds to
kick off a long running ARS. Add a module option to disable this
behavior at initialization time, or at new region discovery time.
Otherwise, ARS can be started manually regardless of the state of this
setting.

ARS is an operation that can take 10s to 100s of seconds to find media
errors that should rarely be present. If the platform crashes due to
media errors in persistent memory, the expectation is that the BIOS will
report those known errors in a 'short' ARS request.
A 'short' ARS request asks platform firmware to return an ARS payload
with all known errors, but without issuing a 'long' scrub. At driver
init a short request is issued to all PMEM ranges before registering
regions. Then, in the background, a long ARS is scheduled for each
region.
The ARS implementation is simplified to centralize ARS completion work
in the ars_complete() helper. The timeout is removed since there is no
facility to cancel ARS, and this otherwise arranges for system init to
never be blocked waiting for a 'long' ARS. The ars_state flags are used
to coordinate ARS requests from driver init, ARS requests from
userspace, and ARS requests in response to media error notifications.
Given that there is no notification of ARS completion the implementation
still needs to poll. It backs off exponentially to a maximum poll period
of 30 minutes.

acpi_nfit_query_poison() is awkward in that it requires an nfit_spa
argument in order to determine what max_ars value to use. Instead probe
for the minimum max_ars across all scrub-capable ranges in the system
and drop the nfit_spa argument.
This enables a larger rework / simplification of the ARS state machine
whereby the status can be retrieved once and then iterated over all
address ranges to reap completions.

This patch adds peliminary device-tree bindings for persistent memory
regions. The driver registers a libnvdimm bus for each pmem-region
node and each address range under the node is converted to a region
within that bus.

We want to be able to cross reference the region and bus devices
with the device tree node that they were spawned from. libNVDIMM
handles creating the actual devices for these internally, so we
need to pass in a pointer to the relevant node in the descriptor.

GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.
Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped
A couple of makefiles mark such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.
.SECONDARY
Prerequisites of this special target are treated as intermediate
files but are never automatically deleted.
.PRECIOUS
When make is interrupted during execution, it may delete the target
file it is updating if the file was modified since make started.
If you mark the file as precious, make will never delete the file
if interrupted.
Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.
The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.
Another difference is that .PRECIOUS works with pattern rules whereas
.SECONDARY does not.
.PRECIOUS: $(obj)/%.lex.c
works, but
.SECONDARY: $(obj)/%.lex.c
has no effect. However, for the reason above, I do not want to use
.PRECIOUS which could cause obscure build breakage.
The targets specified as .SECONDARY must be explicit. $(targets)
contains all targets that need to include .*.cmd files. So, the
intermediates you want to keep are mostly in there. Therefore, mark
$(targets) as .SECONDARY. It means primary targets are also marked
as .SECONDARY, but I do not see any drawback for this.
I replaced some .SECONDARY / .PRECIOUS markers with 'targets'. This
will make Kbuild search for non-existing .*.cmd files, but this is
not a noticeable performance issue.

a DTB as binary data into the kernel image or a module. It is used in
several places in the source tree. Support it in the core Makefile.

At initialization time the 'dimm' driver caches a copy of the memory
device's label area and reserves address space for each of the
namespaces defined.
However, as can be seen below, the reservation occurs even when the
index blocks are invalid:
nvdimm nmem0: nvdimm_init_config_data: len: 131072 rc: 0
nvdimm nmem0: config data size: 131072

nvdimm nmem0: __nd_label_validate: nsindex1 labelsize 1 invalid
nvdimm nmem0: : pmem-6025e505: 0x1000000000 @ 0xf50000000 reserve <-- bad
Gate dpa reservation on the presence of valid index blocks.

Pull rdma updates from Jason Gunthorpe:
"Doug and I are at a conference next week so if another PR is sent I
expect it to only be bug fixes. Parav noted yesterday that there are
some fringe case behavior changes in his work that he would like to
fix, and I see that Intel has a number of rc looking patches for HFI1
they posted yesterday.
Parav is again the biggest contributor by patch count with his ongoing
work to enable container support in the RDMA stack, followed by Leon
doing syzkaller inspired cleanups, though most of the actual fixing
went to RC.
There is one uncomfortable series here fixing the user ABI to actually
work as intended in 32 bit mode. There are lots of notes in the commit
messages, but the basic summary is we don't think there is an actual
32 bit kernel user of drivers/infiniband for several good reasons.
However we are seeing people want to use a 32 bit user space with 64
bit kernel, which didn't completely work today. So in fixing it we
required a 32 bit rxe user to upgrade their userspace. rxe users are
still already quite rare and we think a 32 bit one is non-existing.
- Fix RDMA uapi headers to actually compile in userspace and be more
complete
- Three shared with netdev pull requests from Mellanox:
* 7 patches, mostly to net with 1 IB related one at the back).
This series addresses an IRQ performance issue (patch 1),
cleanups related to the fix for the IRQ performance problem
(patches 2-6), and then extends the fragmented completion queue
support that already exists in the net side of the driver to the
ib side of the driver (patch 7).
* Mostly IB, with 5 patches to net that are needed to support the
remaining 10 patches to the IB subsystem. This series extends
the current 'representor' framework when the mlx5 driver is in
switchdev mode from being a netdev only construct to being a
netdev/IB dev construct. The IB dev is limited to raw Eth queue
pairs only, but by having an IB dev of this type attached to the
representor for a switchdev port, it enables DPDK to work on the
switchdev device.
* All net related, but needed as infrastructure for the rdma
driver
- Updates for the hns, i40iw, bnxt_re, cxgb3, cxgb4, hns drivers
- SRP performance updates
- IB uverbs write path cleanup patch series from Leon
- Add RDMA_CM support to ib_srpt. This is disabled by default. Users
need to set the port for ib_srpt to listen on in configfs in order
for it to be enabled
(/sys/kernel/config/target/srpt/discovery_auth/rdma_cm_port)
- TSO and Scatter FCS support in mlx4
- Refactor of modify_qp routine to resolve problems seen while
working on new code that is forthcoming
- More refactoring and updates of RDMA CM for containers support from
Parav
- mlx5 'fine grained packet pacing', 'ipsec offload' and 'device
memory' user API features
- Infrastructure updates for the new IOCTL interface, based on
increased usage
- ABI compatibility bug fixes to fully support 32 bit userspace on 64
bit kernel as was originally intended. See the commit messages for
extensive details
- Syzkaller bugs and code cleanups motivated by them"

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- DM core passthrough ioctl fix to retain reference to DM table, and
that table's block devices, while issuing the ioctl to one of those
block devices.
- DM core passthrough ioctl fix to _not_ override the fmode_t used to
issue the ioctl. Overriding by using the fmode_t that the block
device was originally open with during DM table load is a liability.
- Add DM core support for secure erase forwarding and update the DM
linear and DM striped targets to support them.
- A DM core 4.16 stable fix to allow abnormal IO (e.g. discard, write
same, write zeroes) for targets that make use of the non-splitting IO
variant (as is done for multipath or thinp when layered directly on
NVMe).
- Allow DM targets to return a payload in response to a DM message that
they are sent. This is useful for DM targets that would like to
provide statistics data in response to DM messages.
- Update DM bufio to support non-power-of-2 block sizes. Numerous other
related changes prepare the DM bufio code for this support.
- Fix DM crypt to use a bounded amount of memory across the entire
system. This is to avoid OOM that can otherwise occur in response to
certain pathological IO workloads (e.g. discarding a large DM crypt
device).
- Add a 'check_at_most_once' feature to the DM verity target to allow
verity to be used on mobile devices that have very limited resources.
- Fix the DM integrity target to fail early if a keyed algorithm (e.g.
HMAC) is to be used but the key isn't set.
- Add non-power-of-2 support to the DM unstripe target.
- Eliminate the use of a Variable Length Array in the DM stripe target.
- Update the DM log-writes target to record metadata (REQ_META flag).
- DM raid fixes for its nosync status and some variable range issues.

In order to enable a PLL, not only the PLL has to be powered up and
locked, but you also have to de-assert the reset signal. The last part
was missing. Add it so PLLs that were not enabled by the FW/bootloader
can be enabled from Linux.

Add a clock driver for the Stratix10 SoC. The driver is similar to the
Cyclone5/Arria10 platforms, with the exception that this driver only uses
one single clock binding.

Add a new pointer argument to cpuidle_select() and to the ->select
cpuidle governor callback to allow a boolean value indicating
whether or not the tick should be stopped before entering the
selected state to be returned from there.
Make the ladder governor ignore that pointer (to preserve its
current behavior) and make the menu governor return 'false" through
it if:
(1) the idle exit latency is constrained at 0, or
(2) the selected state is a polling one, or
(3) the expected idle period duration is within the tick period
range.
In addition to that, the correction factor computations in the menu
governor need to take the possibility that the tick may not be
stopped into account to avoid artificially small correction factor
values. To that end, add a mechanism to record tick wakeups, as
suggested by Peter Zijlstra, and use it to modify the menu_update()
behavior when tick wakeup occurs. Namely, if the CPU is woken up by
the tick and the return value of tick_nohz_get_sleep_length() is not
within the tick boundary, the predicted idle duration is likely too
short, so make menu_update() try to compensate for that by updating
the governor statistics as though the CPU was idle for a long time.
Since the value returned through the new argument pointer of
cpuidle_select() is not used by its caller yet, this change by
itself is not expected to alter the functionality of the code.
