Conflict was two parallel additions of include files to sch_generic.c,
no biggie.

Pull media fixes from Mauro Carvalho Chehab:
"A series of fixes for the media subsytem:
- The largest amount of fixes in this series is with regards to
comments that aren't kernel-doc, but start with "/**".
A new check added for 4.15 makes it to produce a *huge* amount of
new warnings (I'm compiling here with W=1). Most of the patches in
this series fix those.
No code changes - just comment changes at the source files
- rc: some fixed in order to better handle RC repetition codes
- v4l-async: use the v4l2_dev from the root notifier when matching
sub-devices
- v4l2-fwnode: Check subdev count after checking port
- ov 13858 and et8ek8: compilation fix with randconfigs
- usbtv: a trivial new USB ID addition
- dibusb-common: don't do DMA on stack on firmware load
- imx274: Fix error handling, add MAINTAINERS entry

Document the recommended presence of a device-specific compatible value,

This will allow checkpatch to validate compatible values in DTS.
Update the example to match current best practices (generic node name,
specific compatible value first).

Despite commit 55020c8056a8 ("of: Add vendor prefix for ON Semiconductor
Corp.") was made long ago, the latter commit 9f49f6dd0473 ("gpio: pca953x:
add onsemi,pca9654 id") made use of another, undocumented vendor prefix.
Since such prefix doesn't seem to be used in any device trees, I think we
can just fix the "compatible" string in the driver and the bindings and be
done with that...

The PHY devices sometimes do have their reset signal (maybe even power
supply?) tied to some GPIO and sometimes it also does happen that a boot
loader does not leave it deasserted. So far this issue has been attacked
from (as I believe) a wrong angle: by teaching the MAC driver to manipulate
the GPIO in question; that solution, when applied to the device trees, led
to adding the PHY reset GPIO properties to the MAC device node, with one
exception: Cadence MACB driver which could handle the "reset-gpios" prop
in a PHY device subnode. I believe that the correct approach is to teach
the 'phylib' to get the MDIO device reset GPIO from the device tree node
corresponding to this device -- which this patch is doing...
Note that I had to modify the AT803x PHY driver as it would stop working
otherwise -- it made use of the reset GPIO for its own purposes...

"Fixes:
- Drop reference to obsolete maintainer tree
- Fix overflow bug in pmbus driver
- Fix SMBUS timeout problem in jc42 driver
For the SMBUS timeout handling, we had a brief discussion if this
should be considered a bug fix or a feature. Peter says "it fixes real
problems where the application misbehave due to faulty content when
reading from an eeprom", and he needs the patch in his company's v4.14
images. This is good enough for me and warrants backport to stable
kernels"

With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver
is not always capable of avoiding the 25-35 ms timeout as specified by
the SMBUS protocol. This may cause silent corruption of the last bit of
any transfer, e.g. a one is read instead of a zero if the sensor chip
times out. This also affects the eeprom half of the nxp-se97 chip, where
this silent corruption was originally noticed. Other I2C adapters probably
suffer similar issues, e.g. bit-banging comes to mind as risky...
The SMBUS register in the nxp chip is not a standard Jedec register, but
it is not special to the nxp chips either, at least the atmel chips
have the same mechanism. Therefore, do not special case this on the
manufacturer, it is opt-in via the device property anyway.

vm direct limit must be set greater than background limit.
The problem is that both thresh and bg_thresh will be 0 if
available_memory is less than 4 pages when evaluating
global_dirtyable_memory.
While this might be worked around the whole point of the warning is
dubious at best. We do rely on admins to do sensible things when
changing tunable knobs. Dirty memory writeback knobs are not any
special in that regards so revert the warning rather than adding more
hacks to work this around.

The FlexCAN controller can be modelled as little or big endian depending
on SOC design. This device tree property identifies the controller
endianness and the driver reads/writes controller registers based on
that.
This is optional property. i.e. if this property is not present in
device tree node then controller is assumed to be little endian. if this
property is present then controller is assumed to be big endian.

printk specifier %p now hashes all addresses before printing. Sometimes
we need to see the actual unmodified address. This can be achieved using
%lx but then we face the risk that if in future we want to change the
way the Kernel handles printing of pointers we will have to grep through
the already existent 50 000 %lx call sites. Let's add specifier %px as a
clear, opt-in, way to print a pointer and maintain some level of
isolation from all the other hex integer output within the Kernel.
Add printk specifier %px to print the actual unmodified address.

Currently there exist approximately 14 000 places in the kernel where
addresses are being printed using an unadorned %p. This potentially
leaks sensitive information regarding the Kernel layout in memory. Many
of these calls are stale, instead of fixing every call lets hash the
address by default before printing. This will of course break some
users, forcing code printing needed addresses to be updated.
Code that _really_ needs the address will soon be able to use the new
printk specifier %px to print the address.
For what it's worth, usage of unadorned %p can be broken down as
follows (thanks to Joe Perches).
$ git grep -E '%p[^A-Za-z0-9]' | cut -f1 -d"/" | sort | uniq -c
1084 arch

Most places use pwd and rely on $PATH lookup. Moving the remaining
absolute path /bin/pwd users over for consistency.
Also, a reason for doing /bin/pwd -> pwd instead of the other way around
is because I believe build systems should make little assumptions on
host filesystem layout. Case in point, we do this kind of patching
already in NixOS.

The GICv4 architecture doesn't make it easy for save/restore to
work, as it doesn't give any guarantee that the pending state
is written into the pending table.
So let's not take any chance, and let's return an error if
we encounter any LPI that has the HW bit set. In order for
userspace to distinguish this error from other failure modes,
use -EACCES as an error code.

"A few late-arriving docs updates that have no real reason to wait.

enhancement from Willy to generate docs warnings during a kernel build
(but only when additional warnings have been requested in general)"
* tag 'docs-4.15-2' of git://git.lwn.net/linux:
Add optional check for bad kernel-doc comments
Documentation: fix profile= options in kernel-parameters.txt
documentation/svga.txt: update outdated file
kokr/memory-barriers.txt: Fix typo in paring example
kokr/memory-barriers/txt: Replace uses of "transitive"
Documentation/process: add Co-Developed-by: tag for patches with multiple authors
