Pull uaccess unification updates from Al Viro:
"This is the uaccess unification pile. It's _not_ the end of uaccess
work, but the next batch of that will go into the next cycle. This one
mostly takes copy_from_user() and friends out of arch/* and gets the
zero-padding behaviour in sync for all architectures.
Dealing with the nocache/writethrough mess is for the next cycle;
fortunately, that's x86-only. Same for cleanups in iov_iter.c (I am
sold on access_ok() in there, BTW; just not in this pile), same for
reducing __copy_... callsites, strn*... stuff, etc. - there will be a
pile about as large as this one in the next merge window.
This one sat in -next for weeks. -3KLoC"

Pull ACPI updates from Rafael Wysocki:
"These are some device enumeration code changes, updates of the AC and
battery drivers to help them avoid attaching to devices that cannot be
handled by them, new operation region driver for the Intel CHT Whiskey
Cove PMIC, new sysfs entries for CPPC performance capabilities, a new
_REV quirk blacklist entry and a couple of assorted minor fixes and
cleanups.
Specifics:
- Update the core device enumeration code to make it more internally
consistent and robust and drop the force_remove sysfs attribute
that could be used to tell it to ignore errors on device
hot-removal which was dangerous in general and no real and still
relevant use cases for it could be found (Rafael Wysocki, Michal
Hocko).
- Make the core device enumeration code use _PXM to associate
platform devices created by it with specific NUMA nodes (Shanker
Donthineni).
- Extend the CPPC library by adding more sysfs entries for
performance capabilities to it and making it use the lowest
nonlinear performance parameter (Prashanth Prakash).
- Make the CPU online more consistent with CPU initialization in the
ACPI processor driver (Prashanth Prakash).
- Update the AC and battery drivers to help them avoid attaching to
devices that cannot be handled by them and update the
axp288_charger power supply driver to work correctly on ACPI
systems without the INT3496 device (Hans de Goede).
- Add an ACPI operation region driver for the Intel CHT Whiskey Cove
PMIC and update the xpower operation region driver to work without
IIO which isn't really necessary for it to work (Hans de Goede).
- Add a new entry for Dell Inspiron 7537 to the _REV quirk blacklist
(Kai Heng Feng).
- Make the code in the ACPI video driver easier to follow by adding
symbols and comments to it (Dmitry Frank).
- Update ACPI documentation and drop a function that has no users
from the tables-handling code (Cao jin, Baoquan He)"

Pull power management updates from Rafael Wysocki:
"This time the majority of changes go to the cpufreq subsystem (and to
the intel_pstate driver in particular) and there are some updates in
the generic power domains framework, cpuidle, tools and a couple of
other places.
One thing worth mentioning is that the intel_pstate's sysfs interface
has been reworked to be more consistent with the general expectations
of the cpufreq core and less confusing, hopefully for the better.
Also, we have a new cpufreq driver for Tegra186 and new hardware
support in intel_pstata and the Mediatek cpufreq driver.
Apart from that, the AnalyzeSuspend utility for system suspend
profiling gets a companion called AnalyzeBoot for the analogous
profiling of system boot and they both go into one place under
tools/power/pm-graph/.
The rest is mostly fixes, cleanups and code reorganization.
Specifics:
- Rework the intel_pstate driver's sysfs interface to make it more
straightforward and more intuitive (Rafael Wysocki).
- Make intel_pstate support all processors which advertise HWP
(hardware-managed P-states) to the kernel in all operation modes
and make it use the load-based P-state selection algorithm on a
wider range of systems in the active mode (Rafael Wysocki).
- Add cpufreq driver for Tegra186 (Mikko Perttunen).
- Add support for Gemini Lake SoCs to intel_pstate (David Box).
- Add support for MT8176 and MT817x to the Mediatek cpufreq driver
and clean up that driver a bit (Daniel Kurtz).
- Clean up intel_pstate and optimize it slightly (Rafael Wysocki).
- Update the schedutil cpufreq governor, mostly to fix a couple of
issues with it related to specific workloads, and rework its sysfs
tunable and initialization a bit (Rafael Wysocki, Viresh Kumar).
- Fix minor issues in the imx6q, dbx500 and qoriq cpufreq drivers
(Christophe Jaillet, Irina Tirdea, Leonard Crestez, Viresh Kumar,
YuanTian Tang).
- Add file patterns for cpufreq DT bindings to MAINTAINERS (Geert
Uytterhoeven).
- Add support for "always on" power domains to the genpd (generic
power domains) framework and clean up that code somewhat (Ulf
Hansson, Lina Iyer, Viresh Kumar).
- Fix minor issues in the powernv cpuidle driver and clean it up
(Anton Blanchard, Gautham Shenoy).
- Move the AnalyzeSuspend utility under tools/power/pm-graph/ and add
an analogous boot-profiling utility called AnalyzeBoot to it (Todd
Brandt).
- Add rk3328 support to the rockchip-io AVS (Adaptive Voltage
Scaling) driver (David Wu).
- Fix minor issues in the cpuidle core, the intel_pstate_tracer
utility, the devfreq framework and the PM core documentation
(Chanwoo Choi, Doug Smythies, Johan Hovold, Marcin Nowakowski)"

Pull block layer updates from Jens Axboe:
- Add BFQ IO scheduler under the new blk-mq scheduling framework. BFQ
was initially a fork of CFQ, but subsequently changed to implement
fairness based on B-WF2Q+, a modified variant of WF2Q. BFQ is meant
to be used on desktop type single drives, providing good fairness.
From Paolo.
- Add Kyber IO scheduler. This is a full multiqueue aware scheduler,
using a scalable token based algorithm that throttles IO based on
live completion IO stats, similary to blk-wbt. From Omar.
- A series from Jan, moving users to separately allocated backing
devices. This continues the work of separating backing device life
times, solving various problems with hot removal.
- A series of updates for lightnvm, mostly from Javier. Includes a
'pblk' target that exposes an open channel SSD as a physical block
device.
- A series of fixes and improvements for nbd from Josef.
- A series from Omar, removing queue sharing between devices on mostly
legacy drivers. This helps us clean up other bits, if we know that a
queue only has a single device backing. This has been overdue for
more than a decade.
- Fixes for the blk-stats, and improvements to unify the stats and user
windows. This both improves blk-wbt, and enables other users to
register a need to receive IO stats for a device. From Omar.
- blk-throttle improvements from Shaohua. This provides a scalable
framework for implementing scalable priotization - particularly for
blk-mq, but applicable to any type of block device. The interface is
marked experimental for now.
- Bucketized IO stats for IO polling from Stephen Bates. This improves
efficiency of polled workloads in the presence of mixed block size
IO.
- A few fixes for opal, from Scott.
- A few pulls for NVMe, including a lot of fixes for NVMe-over-fabrics.
From a variety of folks, mostly Sagi and James Smart.
- A series from Bart, improving our exposed info and capabilities from
the blk-mq debugfs support.
- A series from Christoph, cleaning up how handle WRITE_ZEROES.
- A series from Christoph, cleaning up the block layer handling of how
we track errors in a request. On top of being a nice cleanup, it also
shrinks the size of struct request a bit.
- Removal of mg_disk and hd (sorry Linus) by Christoph. The former was
never used by platforms, and the latter has outlived it's usefulness.
- Various little bug fixes and cleanups from a wide variety of folks.

The WRITE SAME to TRIM translation rewrites the DATA OUT buffer. While
the SCSI code accomodates for this by passing a read-writable buffer
userspace applications don't cater for this behavior. In fact it can
be used to rewrite e.g. a readonly file through mmap and should be
considered as a security fix.

If the netdev is accessed before the urbs are initialized,
there will be NULL pointer dereferences. That is avoided by
registering it when it is fully initialized.
This case occurs e.g. if dhcpcd is running in the background
and the device is probed, either after insmod hso or
when the device appears on the usb bus.
A backtrace is the following:

On slave list updates, the bonding driver computes its hard_header_len
as the maximum of all enslaved devices's hard_header_len.
If the slave list is empty, e.g. on last enslaved device removal,
ETH_HLEN is used.
Since the bonding header_ops are set only when the first enslaved
device is attached, the above can lead to header_ops->create()
being called with the wrong skb headroom in place.
If bond0 is configured on top of ipoib devices, with the
following commands:
ifup bond0
for slave in $BOND_SLAVES_LIST; do
ip link set dev $slave nomaster
done
ping -c 1 <ip on bond0 subnet>
we will obtain a skb_under_panic() with a similar call trace:

This change addresses the issue avoiding updating the bonding device
hard_header_len when the slaves list become empty, forbidding to
shrink it below the value used by header_ops->create().
The bug is there since commit 54ef31371407 ("[PATCH] bonding: Handle large
hard_header_len") but the panic can be triggered only since
commit fc791b633515 ("IB/ipoib: move back IB LL address into the hard

Tony Lindgren reports a kernel oops that resulted from my compile-time
fix on the default config. This shows two problems:
a) configurations that did not already enable PTP_1588_CLOCK will
now miss the cpts driver
b) when cpts support is disabled, the driver crashes. This is a
preexisting problem that we did not notice before my patch.
While the second problem is still being investigated, this modifies
the dependencies again, getting us back to the original state, with
another 'select NET_PTP_CLASSIFY' added in to avoid the original
link error we got, and the 'depends on POSIX_TIMERS' to hide
the CPTS support when turning it on would be useless.

mtip32xx supposes that 'request_idx' passed to .init_request()

After MQ IO scheduler is in, request tag assigned isn't same with

If a wait_for_completion_timeout() call returns due to a timeout,
complete() can get called after returning from the wait which is
incorrect and can cause subsequent transmissions on a channel to fail.
Since the wait_for_completion_timeout() sees the completion variable
is non-zero caused by the erroneous/spurious complete() call, and
it immediately returns without waiting for the time as expected by the
client.
This patch fixes the issue by skipping complete() call for the timer
expiry.

There exists a race when msg_submit return immediately as there was an
active request being processed which may have completed just before it's
checked again in mbox_send_message. This will result in return to the
caller without waiting in mbox_send_message even when it's blocking Tx.
This patch fixes the issue by waiting for the completion always if Tx
is in blocking mode.

Pull networking fixes from David Miller:
1) MLX5 bug fixes from Saeed Mahameed et al:
- released wrong resources when firmware timeout happens
- fix wrong check for encapsulation size limits
- UAR memory leak
- ETHTOOL_GRXCLSRLALL failed to fill in info->data
2) Don't cache l3mdev on mis-matches local route, causes net devices to
leak refs. From Robert Shearman.
3) Handle fragmented SKBs properly in macsec driver, the problem is
that we were mis-sizing the sgvec table. From Jason A. Donenfeld.
4) We cannot have checksum offload enabled for inner UDP tunneled
packet during IPSEC, from Ansis Atteka.
5) Fix double SKB free in ravb driver, from Dan Carpenter.
6) Fix CPU port handling in b53 DSA driver, from Florian Dainelli.
7) Don't use on-stack buffers for usb_control_msg() in CAN usb driver,
from Maksim Salau.
8) Fix device leak in macvlan driver, from Herbert Xu. We have to purge
the broadcast queue properly on port destroy.
9) Fix tx ring entry limit on EF10 devices in sfc driver. From Bert
Kenward.
10) Fix memory leaks in team driver, from Pan Bian.
11) Don't setup ipv6_stub before it can be actually used, from Paolo
Abeni.
12) Fix tipc socket flow control accounting, from Parthasarathy
Bhuvaragan.
13) Fix crash on module unload in hso driver, from Andreas Kemnade.
14) Fix purging of bridge multicast entries, the problem is that if we
don't defer it to ndo_uninit it's possible for new entries to get
added after we purge. Fix from Xin Long.
15) Don't return garbage for PACKET_HDRLEN getsockopt, from Alexander
Potapenko.
16) Fix autoneg stall properly in PHY layer, and revert micrel driver
change that was papering over it. From Alexander Kochetkov.
17) Don't dereference an ipv4 route as an ipv6 one in the ip6_tunnnel
code, from Cong Wang.
18) Clear out the congestion control private of the TCP socket in all of
the right places, from Wei Wang.
19) rawv6_ioctl measures SKB length incorrectly, fix from Jamie
Bainbridge.

We call skb_cow_data, which is good anyway to ensure we can actually
modify the skb as such (another error from prior). Now that we have the
number of fragments required, we can safely allocate exactly that amount
of memory.

The Ethernet link on an interrupt driven PHY was not coming up if the Ethernet
cable was plugged before the Ethernet interface was brought up.
The patch trigger PHY state machine to update link state if PHY was requested to
do auto-negotiation and auto-negotiation complete flag already set.
During power-up cycle the PHY do auto-negotiation, generate interrupt and set
auto-negotiation complete flag. Interrupt is handled by PHY state machine but
doesn't update link state because PHY is in PHY_READY state. After some time
MAC bring up, start and request PHY to do auto-negotiation. If there are no new
settings to advertise genphy_config_aneg() doesn't start PHY auto-negotiation.
PHY continue to stay in auto-negotiation complete state and doesn't fire
interrupt. At the same time PHY state machine expect that PHY started
auto-negotiation and is waiting for interrupt from PHY and it won't get it.

ide_pm_execute_rq exectures a PM request synchronously, and in the failure
case where it calls __blk_end_request_all it never checks the error field
passed to the end_io callback, so don't bother setting it.
