The PPPIOCDETACH ioctl effectively tries to "close" the given ppp file
before f_count has reached 0, which is fundamentally a bad idea. It
does check 'f_count < 2', which excludes concurrent operations on the
file since they would only be possible with a shared fd table, in which
case each fdget() would take a file reference. However, it fails to
account for the fact that even with 'f_count == 1' the file can still be
linked into epoll instances. As reported by syzbot, this can trivially
be used to cause a use-after-free.
Yet, the only known user of PPPIOCDETACH is pppd versions older than
ppp-2.4.2, which was released almost 15 years ago (November 2003).
Also, PPPIOCDETACH apparently stopped working reliably at around the
same time, when the f_count check was added to the kernel, e.g. see
https://lkml.org/lkml/2002/12/31/83. Also, the current 'f_count < 2'
check makes PPPIOCDETACH only work in single-threaded applications; it
always fails if called from a multithreaded application.
All pppd versions released in the last 15 years just close() the file
descriptor instead.
Therefore, instead of hacking around this bug by exporting epoll
internals to modules, and probably missing other related bugs, just
remove the PPPIOCDETACH ioctl and see if anyone actually notices. Leave
a stub in place that prints a one-time warning and returns EINVAL.

A handful of fixes. I've been queuing them up a bit too long so the list
is longer than it otherwise would have been spread out across a few -rcs.
In general, it's a scattering of fixes across several platforms, nothing
truly serious enough to point out.
There's a slightly larger batch of them for the Davinci platforms due
to work to bring them back to life after some time, so there's a handful
of regressions, some of them going back very far, others more recent.
There's also a few patches fixing DT on Renesas platforms since they
changed some bindings without remaining backwards compatible, splitting
up describing LVDS as a proper bridge instead of having it as part of the
display unit. We could push for them to be backwards compatible with old
device trees, but it's likely to regress eventually if nobody's actually
using said compatibility.

KVM_HINTS_DEDICATED seems to be somewhat confusing:
Guest doesn't really care whether it's the only task running on a host
CPU as long as it's not preempted.
And there are more reasons for Guest to be preempted than host CPU
sharing, for example, with memory overcommit it can get preempted on a
memory access, post copy migration can cause preemption, etc.
Let's call it KVM_HINTS_REALTIME which seems to better
match what guests expect.
Also, the flag most be set on all vCPUs - current guests assume this.
Note so in the documentation.

The micrel KSZ9031 phy has a optional clock pin (CLK125_NDO) which can be
used as reference clock for the MAC unit. The clock signal must meet the
RGMII requirements to ensure the correct data transmission between the
MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle
requirement if the phy is configured as slave. For a complete
describtion look at the errata sheets: DS80000691D or DS80000692D.
The errata sheet recommends to force the phy into master mode whenever
there is a 1000Base-T link-up as work around. Only set the
"micrel,force-master" property if you use the phy reference clock provided
by CLK125_NDO pin as MAC reference clock in your application.
Attenation, this workaround is only usable if the link partner can
be configured to slave mode for 1000Base-T.

Commit af503716ac ("i2c: core: report OF style module alias for devices
registered via OF") fixed how the I2C core reports the module alias when
devices are registered via OF.
But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its
OF device ID table, so if a Device Tree is using a different one, autoload
won't be working for the module (the matching works because the I2C device
ID table is used as a fallback).
So add compatible strings for each of the entries in the I2C device table.

There's a kobject WARN() removal to make syzkaller a lot happier about

There's also some fimware test and documentation fixes, and the

before drivers started to take advantage of it.

As stated in the pull request for the unification of CLOCK_MONOTONIC and
CLOCK_BOOTTIME, it was clear that we might have to revert the change.
As reported by several folks systemd and other applications rely on the
documented behaviour of CLOCK_MONOTONIC on Linux and break with the above
changes. After resume daemons time out and other timeout related issues are
observed. Rafael compiled this list:
* systemd kills daemons on resume, after >WatchdogSec seconds
of suspending (Genki Sky). [Verified that that's because systemd uses
CLOCK_MONOTONIC and expects it to not include the suspend time.]
* systemd-journald misbehaves after resume:
systemd-journald[7266]: File /var/log/journal/016627c3c4784cd4812d4b7e96a34226/system.journal
corrupted or uncleanly shut down, renaming and replacing.
(Mike Galbraith).
* NetworkManager reports "networking disabled" and networking is broken
after resume 50% of the time (Pavel). [May be because of systemd.]
* MATE desktop dims the display and starts the screensaver right after
system resume (Pavel).
* Full system hang during resume (me). [May be due to systemd or NM or both.]
That happens on debian and open suse systems.
It's sad, that these problems were neither catched in -next nor by those
folks who expressed interest in this change.

BPF_PROG_TYPE_SK_MSG programs use a 'void *' for both data and the
data_end pointers. Additionally, the verifier ensures that every
accesses into the values is a __u64 read. This correctly maps on
to the BPF 64-bit architecture.
However, to ensure that when building on 32bit architectures that
clang uses correct types the '-target bpf' option _must_ be
specified. To make this clear add a note to the Documentation.

That prevents the ascii art from being processed as

Pull networking fixes from David Miller:
1) Unbalanced refcounting in TIPC, from Jon Maloy.
2) Only allow TCP_MD5SIG to be set on sockets in close or listen state.
Once the connection is established it makes no sense to change this.

Although we've implemented PSCI 0.1, 0.2 and 1.0, we expose either 0.1
or 1.0 to a guest, defaulting to the latest version of the PSCI
implementation that is compatible with the requested version. This is
no different from doing a firmware upgrade on KVM.
But in order to give a chance to hypothetical badly implemented guests
that would have a fit by discovering something other than PSCI 0.2,
let's provide a new API that allows userspace to pick one particular
version of the API.
This is implemented as a new class of "firmware" registers, where
we expose the PSCI version. This allows the PSCI version to be
save/restored as part of a guest migration, and also set to
any supported version if the guest requires it.
