FUTEX_CMP_REQUEUE_PI was misnamed in two different ways:
FUTEX_REQUEUE_CMP_PI and FUTEX_REQUEUE_PI. The existence of two
different misnamings leaves the reader wondering if we are talking
about two different operations. Furthermore, the misnamings mean
that grepping the source for the correct name (which doesn't
appear at all) won't find this documentation file.

lockdep code has been moved from kernel/ to kernel/locking/ by commit
8eddac3f103736163f49255bcb109edadea167f6 ("locking: Move the lockdep
code to kernel/locking/"). But, path to lockdep code in document was not
updated.

This commit adds a message that is printed if the relevant grace-period
kthread has not been able to run for the two seconds preceding the
stall warning. (The two seconds is double the maximum interval between
successive bouts of quiescent-state forcing.)

Although cond_resched_rcu_qs() only applies to TASKS_RCU, it is used
in places where it would be useful for it to apply to the normal RCU
flavors, rcu_preempt, rcu_sched, and rcu_bh. This is especially the
case for workloads that aggressively overload the system, particularly
those that generate large numbers of RCU updates on systems running
NO_HZ_FULL CPUs. This commit therefore communicates quiescent states
from cond_resched_rcu_qs() to the normal RCU flavors.
Note that it is unfortunately necessary to leave the old ->passed_quiesce
mechanism in place to allow quiescent states that apply to only one
flavor to be recorded. (Yes, we could decrement ->rcu_qs_ctr_snap in
that case, but that is not so good for debugging of RCU internals.)
In addition, if one of the RCU flavor's grace period has stalled, this
will invoke rcu_momentary_dyntick_idle(), resulting in a heavy-weight
quiescent state visible from other CPUs.

The current RCU CPU stall warning code will print "Stall ended before
state dump start" any time that the stall-warning code is triggered on
a CPU that has already reported a quiescent state for the current grace
period and if all quiescent states have been reported for the current
grace period. However, a true stall can result in these symptoms, for
example, by preventing RCU's grace-period kthreads from ever running
This commit therefore checks for this condition, reporting the end of
the stall only if one of the grace-period counters has actually advanced.
Otherwise, it reports the last time that the grace-period kthread made
meaningful progress. (In normal situations, the grace-period kthread
should make meaningful progress at least every jiffies_till_next_fqs
jiffies.)

This commit documents the fact that it is not safe to use bitfields
as shared variables in synchronization algorithms. It also documents
that CPUs must be able to concurrently load from and store to adjacent
one-byte and two-byte variables, which is in fact required by the
C11 standard (Section 3.14).

moved the rcu_cpu_stall_timeout module parameter from rcutree.c to
rcupdate.c, but failed to update Documentation/RCU/stallwarn.txt. This
commit therefore repairs this omission.

Pull regulator updates from Mark Brown:
"This has not been a busy release for the regulator framework, though
we do have the first parts of some ongoing work from Bjorn Andersson
to allow us to support more complex modern systems with dynamic
configuration of regulators in suspend and idle states.
- Support for device-specific properties on regulator nodes when
using simplified DT parsing in the core from Krzysztof Kozlowski.
- Restructuring of the load tracking code, intended to support future
improvements in this area for more complex system designs.
- New drivers for Maxim MAX77843 and Mediatek MT6397.
- Lots of smaller fixes and improvements"

"isil" and "isl" prefixes are used at various locations inside the kernel
to reference Intersil corporation. This patch is part of a series fixing
those locations were "isl" is used in compatible strings to use the now
expected "isil" prefix instead (NASDAQ symbol for Intersil and most used
version). The old compatible string is kept for backward compatibility.

Pull spi updates from Mark Brown:
"The major highlight this release is a refactoring of the core to allow
us to run synchronous transfers in the context of the caller when
there is no contention for the bus. This improves performance in the
very common case by eliminating context switches and reducing the
number of hardware setup and teardown operations we need to perform.
Other changes:
- New drivers for DLN-2 USB-SPI adapter and ST SPI controllers.
- A big round of cleanups, performance and feature improvements for
the xilinx driver from Ricardo Ribalda Delgado.
- A wide range of smaller cleanups, fixes and feature improvements
throughout the subsystem"

This attribute allows to configure the update interval of ina226. Although
the bus and shunt voltage conversion times remain hardcoded to 1.1 ms, we can
now modify said interval by changing the averaging rate.
While we're at it - add an additional variable to ina2xx_data, which holds
the current configuration settings - this way we'll be able to restore the
configuration in case of an unexpected chip reset.

The shunt resistance can only be set via platform_data or device tree. This
isn't suitable for devices in which the shunt resistance can change/isn't
known at boot-time.
Add a sysfs attribute that allows to read and set the shunt resistance.

Pull networking fixes from David Miller:
1) Stretch ACKs can kill performance with Reno and CUBIC congestion
control, largely due to LRO and GRO. Fix from Neal Cardwell.
2) Fix userland breakage because we accidently emit zero length netlink
messages from the bridging code. From Roopa Prabhu.
3) Carry handling in generic csum_tcpudp_nofold is broken, fix from
Karl Beldan.
4) Remove bogus dev_set_net() calls from CAIF driver, from Nicolas
Dichtel.
5) Make sure PPP deflation never returns a length greater then the
output buffer, otherwise we overflow and trigger skb_over_panic().
Fix from Florian Westphal.
6) COSA driver needs VIRT_TO_BUS Kconfig dependencies, from Arnd
Bergmann.
7) Don't increase route cached MTU on datagram too big ICMPs. From Li
Wei.
8) Fix error path leaks in nf_tables, from Pablo Neira Ayuso.
9) Fix bitmask handling regression in netlink that broke things like
acpi userland tools. From Pablo Neira Ayuso.
10) Wrong header pointer passed to param_type2af() in SCTP code, from
Saran Maruti Ramanara.
11) Stacked vlans not handled correctly by vlan_get_protocol(), from
Toshiaki Makita.
12) Add missing DMA memory barrier to xgene driver, from Iyappan
Subramanian.
13) Fix crash in rate estimators, from Eric Dumazet.
14) We've been adding various workarounds, one after another, for the
change which added the per-net tcp_sock. It was meant to reduce
socket contention but added lots of problems.
Reduce this instead to a proper per-cpu socket and that rids us of
all the daemons.
From Eric Dumazet.
15) Fix memory corruption and OOPS in mlx4 driver, from Jack
Morgenstein.
16) When we disabled UFO in the virtio_net device, it introduces some
serious performance regressions. The orignal problem was IPV6
fragment ID generation, so fix that properly instead. From Vlad
Yasevich.
17) sr9700 driver build breaks on xtensa because it defines macros with
the same name as those used by the arch code. Use more unique
names. From Chen Gang.
18) Fix endianness in new virio 1.0 mode of the vhost net driver, from
Michael S Tsirkin.
19) Several sysctls were setting the maxlen attribute incorrectly, from
Sasha Levin.
20) Don't accept an FQ scheduler quantum of zero, that leads to crashes.
From Kenneth Klette Jonassen.
21) Fix dumping of non-existing actions in the packet scheduler
classifier. From Ignacy Gawędzki.
22) Return the write work_done value when doing TX work in the qlcnic
driver.
23) ip6gre_err accesses the info field with the wrong endianness, from
Sabrina Dubroca.

The QEMU open source machine emulator and virtualizer presents firmware
and operating systems running in virtual machines ("guests") with purely
virtual hardware (ie. hardware that has never existed in physical form).
Since QEMU exposes some of these devices in a DTB, it makes sense to
define "qemu" and "virtio" as vendor prefixes.
The qemu definition is from [1], revision 4451 (22:24, 25 November 2014).
The virtio definition is composed from [2] and [3].

Peter Maydell suggested that we describe new devices / DTB nodes in the
kernel Documentation tree that we expose to arm "virt" guests in QEMU.
Although the kernel is not required to access the fw_cfg interface,
"Documentation/devicetree/bindings/arm" is probably the best central spot
to keep the fw_cfg description in.

Current vendor-prefixes.txt already has "ak" prefix for Asahi Kasei Corp
by ae8c4209af2c(of: Add vendor prefix for Asahi Kasei Corp.)
It went through the appropriate review process. But, almost all
Asahi Kasei chip drivers are using "asahi-kasei" prefix today.
(arch/arm/boot/dts/tegra20-seaboard.dts only is using "ak,ak8975",
but there are instances of "asahi-kasei,ak8975" in other dts files.
And drivers/iio/magnetometer/ak8975.c doesn't support "ak,ak8975" prefix)
So, we made a mistake there.
In addition, checkpatch.pl reports WARNING if it is using "asahi-kasei"
prerfix in DT file.
(DT compatible string vendor "asahi-kasei" appears un-documented)
Marking it deprecated and warning with checkpatch is certainly
preferable. So, this patch replace "ak" to "asahi-kasei" in
vendor-prefixes.txt. (and fixup tegra20-seaboard)
OTOH, Asahi Kasei is usually referred to as "AKM", but this patch
doesn't care about it. Because no DT is using that today.

On some laptops, keyboard needs to be reset in order to successfully detect
touchpad (e.g., some Gigabyte laptop models with Elantech touchpads).
Without resettin keyboard touchpad pretends to be completely dead.
Based on the original patch by Mateusz Jończyk this version has been
expanded to include DMI based detection & application of the fix
automatically on the affected models of laptops. This has been confirmed to
fix problem by three users already on three different models of laptops.
