Pull regulator updates from Mark Brown:
"This is a quiet release in terms of code volume but a fairly big one
in terms of framework changes - we've got one long awaited feature in
the form of runtime configuration of suspend and the start of coupled
regulator support too:
- Support for modifying the voltage and enable configuration devices
will have in suspend, contributed by Chunyan Zhang.
- Support for the Spreadtrum SC2731, contributed by Erick Chen.
- The start of changes to support coupled regulators from Maciej
Purski, the rest of the series should arrive for v4.17"

Pull MMC updates from Ulf Hansson:
"There are two major achievements for MMC in this release, which
deserves to be specially highlighted.
First, we have converted the MMC block device from using the legacy
blk interface into using the modern blkmq interface. Not only do we
get all the nice effects from using blkmq, but it also means that new
fresh nice code replaces old rusty code. Great news to everybody that
cares about MMC/SD!
It should also be noted that converting to blkmq has not been trivial,
mostly because of that we have been carrying too much of MMC specific
optimizations for the I/O request path, rather than striving to move
these to the generic blk layer. Hopefully we won't be doing that
mistake, ever again.
Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro),
who both have been working on this for quite some time!
Second, on top of the blkmq deployment, we have enabled full support
the eMMC command queuing feature, introduced in the eMMC v.5.1 spec.
This also includes an implementation of a host driver library,
supporting the corresponding CQHCI HW. Ideally, those controllers that
supports CQHCI should only need some minor adaptations to make this
play.
So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan
driver used on Rockchip RK3399, have enabled support for eMMC command
queueing.
Worth to highlight is also that, implementing the eMMC command queuing
support has been a collaborative effort, as several people from
Codeaurora, Rockchip, Intel and Linaro have been involved. However,
the work has been driven by Adrian Hunter (Intel).
In some shadow of the above, here are the rest of the highlights:
MMC core:
- Don't remove non-removable cards during system suspend
- Add a slot-gpio helper to check capability of GPIO WP detection
MMC host:
- sdhci: Cleanups and improvements of some wakeup related code
- sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy
- sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT
- sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400
- sdhci_f_sdh30: Add ACPI support
- sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume
- sdhci-of-esdhc: A few minor fixes
- mmci: Add support for new STM32 variant
- renesas_sdhi: enable R-Car D3 (r8a77995) support
- tmio/renesas_sdhi: Re-structuring, cleanups and modernizations"

Move the last used path to the end of the list (least preferred) so that
ties are more evenly distributed.
For example, in case with three paths with one that is slower than
others, the remaining two would be unevenly used if they tie. This is
due to the rotation not being a truely fair distribution.
Illustrated: paths a, b, c, 'c' has 1 outstanding IO, a and b are 'tied'
Three possible rotations:
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
...
So 'a' is used 2x more than 'b', although they should be used evenly.
With this change, the most recently used path is always the least
preferred, removing this bias resulting in even distribution.
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
(c, b, a) -> best path 'b'

Since the unstripe target takes a target length which is the
size of *one* striped member we're trying to expose, not the
total size of *all* the striped members, the check does not
make sense and fails for some striped setups.
For example, say we have a 4TB striped device:
or 3907018496 sectors per underlying device:
if (sector_div(width, uc->stripes)) :
3907018496 / 2(num stripes) == 1953509248
tmp_len = width;
if (sector_div(tmp_len, uc->chunk_size)) :
1953509248 / 256(chunk size) == 7630895.5
(fails)
Fix this by removing the first check which isn't valid for unstriping.

The 'verify_rq_based:' code in dm_table_determine_type() was checking
all devices in the DM table rather than only checking the data devices.
Fix this by using the immutable target's iterate_devices method.
Also, tweak the block of dm_table_determine_type() code that decides
whether to upgrade from DM_TYPE_BIO_BASED to DM_TYPE_NVME_BIO_BASED so
that it makes sure the immutable_target doesn't support require
splitting IOs.
These changes have been verified to allow a "thin-pool" target whose
data device is an NVMe device to be upgraded to DM_TYPE_NVME_BIO_BASED.
Using the thin-pool in NVMe bio-based mode was verified to pass all the
device-mapper-test-suite's "thin-provisioning" tests.
Also verified that request-based DM multipath (with queue_mode "rq" and
"mq") works as expected using the 'mptest' harness.

Add DM_ENDIO_DELAY_REQUEUE to allow request-based multipath's
multipath_end_io() to instruct dm-rq.c:dm_done() to delay a requeue.
This is beneficial to do if BLK_STS_RESOURCE is returned from the target
(because target is busy).
Relative to blk-mq: kick the hw queues via blk_mq_requeue_work(),
indirectly from dm-rq.c:__dm_mq_kick_requeue_list(), after a delay.
For old .request_fn: use blk_delay_queue().
bio-based multipath doesn't have feature parity with request-based for
retryable error requeues; that is something that'll need fixing in the
future.

Pull power management updates from Rafael Wysocki:
"This includes some infrastructure changes in the PM core, mostly
related to integration between runtime PM and system-wide suspend and
hibernation, plus some driver changes depending on them and fixes for
issues in that area which have become quite apparent recently.
Also included are changes making more x86-based systems use the Low
Power Sleep S0 _DSM interface by default, which turned out to be
necessary to handle power button wakeups from suspend-to-idle on
Surface Pro3.
On the cpufreq front we have fixes and cleanups in the core, some new
hardware support, driver updates and the removal of some unused code
from the CPU cooling thermal driver.
Apart from this, the Operating Performance Points (OPP) framework is
prepared to be used with power domains in the future and there is a
usual bunch of assorted fixes and cleanups.
Specifics:
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).
- Make the PM core carry out optimizations for devices with driver PM
flags set in some cases and make a few drivers set those flags
(Rafael Wysocki).
- Fix and clean up wrapper routines allowing runtime PM device
callbacks to be re-used for system-wide PM, change the generic
power domains (genpd) framework to stop using those routines
incorrectly and fix up a driver depending on that behavior of genpd
(Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
- Fix and clean up the PM core's device wakeup framework and
re-factor system-wide PM core code related to device wakeup
(Rafael Wysocki, Ulf Hansson, Brian Norris).
- Make more x86-based systems use the Low Power Sleep S0 _DSM
interface by default (to fix power button wakeup from
suspend-to-idle on Surface Pro3) and add a kernel command line
switch to tell it to ignore the system sleep blacklist in the ACPI
core (Rafael Wysocki).
- Fix a race condition related to cpufreq governor module removal and
clean up the governor management code in the cpufreq core (Rafael
Wysocki).
- Drop the unused generic code related to the handling of the static
power energy usage model in the CPU cooling thermal driver along
with the corresponding documentation (Viresh Kumar).
- Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh
Cheng).
- Add a new operating point to the imx6ul and imx6q cpufreq drivers
and switch the latter to using clk_bulk_get() (Anson Huang, Dong
Aisheng).
- Add support for multiple regulators to the TI cpufreq driver along
with a new DT binding related to that and clean up that driver
somewhat (Dave Gerlach).
- Fix a powernv cpufreq driver regression leading to incorrect CPU
frequency reporting, fix that driver to deal with non-continguous
P-states correctly and clean it up (Gautham Shenoy, Shilpasri
Bhat).
- Add support for frequency scaling on Armada 37xx SoCs through the
generic DT cpufreq driver (Gregory CLEMENT).
- Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
- Fix a transition delay setting regression in the longhaul cpufreq
driver (Viresh Kumar).
- Add Skylake X (server) support to the intel_pstate cpufreq driver
and clean up that driver somewhat (Srinivas Pandruvada).
- Clean up the cpufreq statistics collection code (Viresh Kumar).
- Drop cluster terminology and dependency on physical_package_id from
the PSCI driver and drop dependency on arm_big_little from the SCPI
cpufreq driver (Sudeep Holla).
- Add support for system-wide suspend and resume to the RAPL power
capping driver and drop a redundant semicolon from it (Zhen Han,
Luis de Bethencourt).

The ib_write_umad() is protected by taking the umad file mutex.
However, it accesses file->port->ib_dev -- which is protected only by the
port's mutex (field file_mutex).
The ib_umad_remove_one() calls ib_umad_kill_port() which sets
port->ib_dev to NULL under the port mutex (NOT the file mutex).
It then sets the mad agent to "dead" under the umad file mutex.
This is a race condition -- because there is a window where
port->ib_dev is NULL, while the agent is not "dead".
As a result, we saw stack traces like:

In the above trace, ib_umad_write is trying to dereference the NULL
file->port->ib_dev pointer.
Fix this by using the agent's device pointer (the device field
in struct ib_mad_agent) -- which IS protected by the umad file mutex.

Calling fan related SMM functions implemented by Dell BIOS firmware on Dell

Unfortunately, it is unlikely for Dell to fix this since the machine
is pretty old, so this commit just disables fan support to make the
system usable again.

Pull networking fixes from David Miller:
1) The per-network-namespace loopback device, and thus its namespace,
can have its teardown deferred for a long time if a kernel created
TCP socket closes and the namespace is exiting meanwhile. The kernel
keeps trying to finish the close sequence until it times out (which
takes quite some time).
Fix this by forcing the socket closed in this situation, from Dan
Streetman.
2) Fix regression where we're trying to invoke the update_pmtu method
on route types (in this case metadata tunnel routes) that don't
implement the dst_ops method. Fix from Nicolas Dichtel.
3) Fix long standing memory corruption issues in r8169 driver by
performing the chip statistics DMA programming more correctly. From
Francois Romieu.
4) Handle local broadcast sends over VRF routes properly, from David
Ahern.
5) Don't refire the DCCP CCID2 timer endlessly, otherwise the socket
can never be released. From Alexey Kodanev.
6) Set poll flags properly in VSOCK protocol layer, from Stefan
Hajnoczi.

get_user_pages() must be called with mmap_sem held, currently
it is not. In fact it is called under the user db_table->mutex.
To fix this we can convert gup to use the fast alternative,
and safely avoid taking mmap_sem, if possible. Furthermore
this is safe wrt to the mutex as other callers that take the
lock (unmap and alloc_db) are not called under mmap_sem
(hence possible deadlock).
