doc: don't use deprecated "---help---" markers in target docs
I'm not convinced the script makes useful automaed help lines anyway,
but since we're trying to deprecate the use of "---help---" in Kconfig
files, let's fix the doc example code too.

Merge branch 'i2c/for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "I2C has quite some patches for you this time. I hope it is the move to per-driver-maintainers which is now showing results. We will see. The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI), larger refactoring of the Designware, Tegra, and PXA drivers, the Cadence driver supports being a slave now, and there is support to instanciate SPD eeproms for well-known cases (which will be user-visible because the i801 driver supports it), and some devm_platform_ioremap_resource() conversions which blow up the diffstat. Note that I applied the Nuvoton driver quite late, so some minor fixup patches arrived during the merge window.

Pull notification queue from David Howells:
"This adds a general notification queue concept and adds an event
source for keys/keyrings, such as linking and unlinking keys and
changing their attributes.
Thanks to Debarshi Ray, we do have a pull request to use this to fix a
problem with gnome-online-accounts - as mentioned last time:
https://gitlab.gnome.org/GNOME/gnome-online-accounts/merge_requests/47
Without this, g-o-a has to constantly poll a keyring-based kerberos
cache to find out if kinit has changed anything.
[ There are other notification pending: mount/sb fsinfo notifications
for libmount that Karel Zak and Ian Kent have been working on, and
Christian Brauner would like to use them in lxc, but let's see how
this one works first ]
LSM hooks are included:
- A set of hooks are provided that allow an LSM to rule on whether or
not a watch may be set. Each of these hooks takes a different
"watched object" parameter, so they're not really shareable. The
LSM should use current's credentials. [Wanted by SELinux & Smack]
- A hook is provided to allow an LSM to rule on whether or not a
particular message may be posted to a particular queue. This is
given the credentials from the event generator (which may be the
system) and the watch setter. [Wanted by Smack]
I've provided SELinux and Smack with implementations of some of these
hooks.
WHY
===
Key/keyring notifications are desirable because if you have your
kerberos tickets in a file/directory, your Gnome desktop will monitor
that using something like fanotify and tell you if your credentials
cache changes.
However, we also have the ability to cache your kerberos tickets in
the session, user or persistent keyring so that it isn't left around
on disk across a reboot or logout. Keyrings, however, cannot currently
be monitored asynchronously, so the desktop has to poll for it - not
so good on a laptop. This facility will allow the desktop to avoid the
need to poll.
DESIGN DECISIONS
================
- The notification queue is built on top of a standard pipe. Messages
are effectively spliced in. The pipe is opened with a special flag:
pipe2(fds, O_NOTIFICATION_PIPE);
The special flag has the same value as O_EXCL (which doesn't seem
like it will ever be applicable in this context)[?]. It is given up
front to make it a lot easier to prohibit splice&co from accessing
the pipe.
[?] Should this be done some other way? I'd rather not use up a new
O_* flag if I can avoid it - should I add a pipe3() system call
instead?
The pipe is then configured::
ioctl(fds[1], IOC_WATCH_QUEUE_SET_SIZE, queue_depth);
ioctl(fds[1], IOC_WATCH_QUEUE_SET_FILTER, &filter);
Messages are then read out of the pipe using read().
- It should be possible to allow write() to insert data into the
notification pipes too, but this is currently disabled as the
kernel has to be able to insert messages into the pipe *without*
holding pipe->mutex and the code to make this work needs careful
auditing.
- sendfile(), splice() and vmsplice() are disabled on notification
pipes because of the pipe->mutex issue and also because they
sometimes want to revert what they just did - but one or more
notification messages might've been interleaved in the ring.
- The kernel inserts messages with the wait queue spinlock held. This
means that pipe_read() and pipe_write() have to take the spinlock
to update the queue pointers.
- Records in the buffer are binary, typed and have a length so that
they can be of varying size.
This allows multiple heterogeneous sources to share a common
buffer; there are 16 million types available, of which I've used
just a few, so there is scope for others to be used. Tags may be
specified when a watchpoint is created to help distinguish the
sources.
- Records are filterable as types have up to 256 subtypes that can be
individually filtered. Other filtration is also available.
- Notification pipes don't interfere with each other; each may be
bound to a different set of watches. Any particular notification
will be copied to all the queues that are currently watching for it
- and only those that are watching for it.
- When recording a notification, the kernel will not sleep, but will
rather mark a queue as having lost a message if there's
insufficient space. read() will fabricate a loss notification
message at an appropriate point later.
- The notification pipe is created and then watchpoints are attached
to it, using one of:
keyctl_watch_key(KEY_SPEC_SESSION_KEYRING, fds[1], 0x01);
watch_mount(AT_FDCWD, "/", 0, fd, 0x02);
watch_sb(AT_FDCWD, "/mnt", 0, fd, 0x03);
where in both cases, fd indicates the queue and the number after is
a tag between 0 and 255.
- Watches are removed if either the notification pipe is destroyed or
the watched object is destroyed. In the latter case, a message will
be generated indicating the enforced watch removal.
Things I want to avoid:
- Introducing features that make the core VFS dependent on the
network stack or networking namespaces (ie. usage of netlink).
- Dumping all this stuff into dmesg and having a daemon that sits
there parsing the output and distributing it as this then puts the
responsibility for security into userspace and makes handling
namespaces tricky. Further, dmesg might not exist or might be
inaccessible inside a container.
- Letting users see events they shouldn't be able to see.
TESTING AND MANPAGES
====================
- The keyutils tree has a pipe-watch branch that has keyctl commands
for making use of notifications. Proposed manual pages can also be
found on this branch, though a couple of them really need to go to
the main manpages repository instead.
If the kernel supports the watching of keys, then running "make
test" on that branch will cause the testing infrastructure to spawn
a monitoring process on the side that monitors a notifications pipe
for all the key/keyring changes induced by the tests and they'll
all be checked off to make sure they happened.
https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/keyutils.git/log/?h=pipe-watch
- A test program is provided (samples/watch_queue/watch_test) that
can be used to monitor for keyrings, mount and superblock events.
Information on the notifications is simply logged to stdout"

The Kernel Concurrency Sanitizer (KCSAN)
KCSAN is a dynamic race detector, which relies on compile-time instrumentation, and uses a watchpoint-based sampling approach to detect races. The feature was under development for quite some time and has already found legitimate bugs. Unfortunately it comes with a limitation, which was only understood late in the development cycle: It requires an up to date CLANG-11 compiler CLANG-11 is not yet released (scheduled for June), but it's the only compiler today which handles the kernel requirements and especially the annotations of functions to exclude them from KCSAN instrumentation correctly. These annotations really need to work so that low level entry code and especially int3 text poke handling can be completely isolated. A detailed discussion of the requirements and compiler issues can be found here: https://lore.kernel.org/lkml/CANpmjNMTsY_8241bS7=XAfqvZHFLrVEkv_uM4aDUWE_kh3Rvbw@mail.gmail.com/ We came to the conclusion that trying to work around compiler limitations and bugs again would end up in a major trainwreck, so requiring a working compiler seemed to be the best choice. For Continous Integration purposes the compiler restriction is manageable and that's where most xxSAN reports come from. For a change this limitation might make GCC people actually look at their bugs. Some issues with CSAN in GCC are 7 years old and one has been 'fixed' 3 years ago with a half baken solution which 'solved' the reported issue but not the underlying problem. The KCSAN developers also ponder to use a GCC plugin to become independent, but that's not something which will show up in a few days. Blocking KCSAN until wide spread compiler support is available is not a really good alternative because the continuous growth of lockless optimizations in the kernel demands proper tooling support. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl7im98THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoQ3xD/9+q87OmwnyoRTs6O3GDDbWZYoJGolh rctDOAYW8RSS73Fiw23z8hKlLl9tJCya6/X8Q9qoonB1YeIEPPRVj5HJWAMUNEIs YgjlZJFmh+mnbP/KQFctm3AWpoX8kqt3ncqj6zG72oQ9qKui691BY/2NmGVSLxUV DqtUYSKmi51XEQtZuXRuHEf3zBxoyeD43DaSCdJAXd6f5O2X7tmrWDuazHVeKzHV lhijvkyBvGMWvPg0IBrXkkLmeOvS0++MTGm3o+L72XF6nWpzTkcV7N0E9GEDFg45 zwcidRVKD5d/1DoU5Tos96rCJpBEGh/wimlu0z14mcZpNiJgRQH5rzVEO9Y14UcP KL9FgRrb5dFw7yfX2zRQ070OFJ4AEDBMK0o5Lbu/QO5KLkvFkqnuWlQfmmtZJWCW DTRw/FgUgU7lvyPjRrao6HBvwy+yTb0u9K5seCOTRkuepR9nPJs0710pFiBsNCfV RY3cyggNBipAzgBOgLxixnq9+rHt70ton6S8Gijxpvt0dGGfO8k0wuEhFtA4zKrQ 6HGK+pidxnoVdEgyQZhS+qzMMkyiUL0FXdaGJ2IX+/DC+Ij1UrUPjZBn7v25M0hQ ESkvxWKCn7snH4/NJsNxqCV1zyEc3zAW/WvLJUc9I7H8zPwtVvKWPrKEMzrJJ5bA aneySilbRxBFUg== =iplm -----END PGP SIGNATURE----- Merge tag 'locking-kcsan-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull the Kernel Concurrency Sanitizer from Thomas Gleixner: "The Kernel Concurrency Sanitizer (KCSAN) is a dynamic race detector, which relies on compile-time instrumentation, and uses a watchpoint-based sampling approach to detect races.

lib/lzo: fix ambiguous encoding bug in lzo-rle
In some rare cases, for input data over 32 KB, lzo-rle could encode two different inputs to the same compressed representation, so that decompression is then ambiguous (i.e. data may be corrupted - although zram is not affected because it operates over 4 KB pages). This modifies the compressor without changing the decompressor or the bitstream format, such that: - there is no change to how data produced by the old compressor is decompressed - an old decompressor will correctly decode data from the updated compressor - performance and compression ratio are not affected - we avoid introducing a new bitstream format In testing over 12.8M real-world files totalling 903 GB, three files were affected by this bug. I also constructed 37M semi-random 64 KB files totalling 2.27 TB, and saw no affected files. Finally I tested over files constructed to contain each of the ~1024 possible bad input sequences; for all of these cases, updated lzo-rle worked correctly. There is no significant impact to performance or compression ratio.

dt-bindings: Fix more incorrect 'reg' property sizes in examples
The examples template is a 'simple-bus' with a size of 1 cell for had between 2 and 4 cells which really only errors on I2C or SPI type devices with a single cell.

dt-bindings: phy: qcom: Fix missing 'ranges' and example addresses
The QCom QMP PHY bindings have child nodes with translatable (MMIO)
addresses, so a 'ranges' property is required in the parent node.
Additionally, the examples default to 1 address and size cell, so let's
fix that, too.

dt-bindings: Remove more cases of 'allOf' containing a '$ref'
Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org> |

Merge branch 'rwonce/rework' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux
Pull READ/WRITE_ONCE rework from Will Deacon:
"This the READ_ONCE rework I've been working on for a while, which
bumps the minimum GCC version and improves code-gen on arm64 when
stack protector is enabled"
[ Side note: I'm _really_ tempted to raise the minimum gcc version to
4.9, so that we can just say that we require _Generic() support.
That would allow us to more cleanly handle a lot of the cases where we
depend on very complex macros with 'sizeof' or __builtin_choose_expr()
with __builtin_types_compatible_p() etc.
This branch has a workaround for sparse not handling _Generic(),
either, but that was already fixed in the sparse development branch,
so it's really just gcc-4.9 that we'd require. - Linus ]
* 'rwonce/rework' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux:
compiler_types.h: Use unoptimized __unqual_scalar_typeof for sparse
compiler_types.h: Optimize __unqual_scalar_typeof compilation time

compiler-types.h: Include naked type in __pick_integer_type() match
READ_ONCE: Fix comment describing 2x32-bit atomicity
gcov: Remove old GCC 3.4 support
arm64: barrier: Use '__unqual_scalar_typeof' for acquire/release macros
locking/barriers: Use '__unqual_scalar_typeof' for load-acquire macros
READ_ONCE: Drop pointer qualifiers when reading from scalar types
READ_ONCE: Enforce atomicity for {READ,WRITE}_ONCE() memory accesses
READ_ONCE: Simplify implementations of {READ,WRITE}_ONCE()
arm64: csum: Disable KASAN for do_csum()
fault_inject: Don't rely on "return value" from WRITE_ONCE()

This time around we have 4 lines of diff in the core framework, removing a
function that isn't used anymore. Otherwise the main new thing for the common
clk framework is that it is selectable in the Kconfig language now. Hopefully
this will let clk drivers and clk consumers be testable on more than the
architectures that support the clk framework. The goal is to introduce some
Kunit tests for the framework.
Outside of the core framework we have the usual set of various driver updates
and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the
largest addition this time around in terms of lines of code. After that the x86
(Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or
upcoming SoCs. After that the dirstat shows the usual suspects working on their
SoC support by fixing minor bugs, correcting data and converting some of their
DT bindings to YAML.
Core:
- Allow the COMMON_CLK config to be selectable
New Drivers:
- Clk driver for Baikal-T1 SoCs
- Mediatek MT6765 clock support
- Support for Intel Agilex clks
- Add support for X1830 and X1000 Ingenic SoC clk controllers
- Add support for the new Renesas RZ/G1H (R8A7742) SoC
- Add support for Qualcomm's MSM8939 Generic Clock Controller
Updates:
- Support IDT VersaClock 5P49V5925
- Bunch of updates for HSDK clock generation unit (CGU) driver
- Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
- Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
- Enable supply regulators for GPU gdscs on Qualcomm SoCs
- Add support for Si5342, Si5344 and Si5345 chips
- Support custom flags in Xilinx zynq firmware
- Various small fixes to the Xilinx clk driver
- A single minor rounding fix for the legacy Allwinner clock support
- A few patches from Abel Vesa as preparation of adding audiomix clock support
on i.MX
- A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and clk-pllv3
drivers
- Drop dependency on ARM64 for i.MX8M clock driver, to support aarch32 mode on
aarch64 hardware
- A series from Peng Fan to improve i.MX8M clock drivers, using composite
clock for core and bus clk slice
- Set a better parent clock for flexcan on i.MX6UL to support CiA102 defined
bit rates
- A couple changes for EMC frequency scaling on Tegra210
- Support for CPU frequency scaling on Tegra20/Tegra30
- New clk gate for CSI test pattern generator on Tegra210
- Regression fixes for Samsung exynos542x and exynos5433 SoCs
- Use of fallthrough; attribute for Samsung s3c24xx
- Updates and fixup HDMI and video clocks on Meson8b
- Fixup reset polarity on Meson8b
- Fix GPU glitch free mux switch on Meson gx and g12
- A minor fix for the currently unused suspend/resume handling on Renesas RZ/A1 and RZ/A2
- Two more conversions of Renesas DT bindings to json-schema
- Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"This time around we have four lines of diff in the core framework,
removing a function that isn't used anymore. Otherwise the main new
thing for the common clk framework is that it is selectable in the
Kconfig language now. Hopefully this will let clk drivers and clk
consumers be testable on more than the architectures that support the
clk framework. The goal is to introduce some Kunit tests for the
framework.
Outside of the core framework we have the usual set of various driver
updates and non-critical fixes. The dirstat shows that the new
Baikal-T1 driver is the largest addition this time around in terms of
lines of code. After that the x86 (Intel), Qualcomm, and Mediatek
drivers introduce many lines to support new or upcoming SoCs. After
that the dirstat shows the usual suspects working on their SoC support
by fixing minor bugs, correcting data and converting some of their DT
bindings to YAML.
Core:
- Allow the COMMON_CLK config to be selectable
New Drivers:
- Clk driver for Baikal-T1 SoCs
- Mediatek MT6765 clock support
- Support for Intel Agilex clks
- Add support for X1830 and X1000 Ingenic SoC clk controllers
- Add support for the new Renesas RZ/G1H (R8A7742) SoC
- Add support for Qualcomm's MSM8939 Generic Clock Controller
Updates:
- Support IDT VersaClock 5P49V5925
- Bunch of updates for HSDK clock generation unit (CGU) driver
- Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
- Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
- Enable supply regulators for GPU gdscs on Qualcomm SoCs
- Add support for Si5342, Si5344 and Si5345 chips
- Support custom flags in Xilinx zynq firmware
- Various small fixes to the Xilinx clk driver
- A single minor rounding fix for the legacy Allwinner clock support
- A few patches from Abel Vesa as preparation of adding audiomix
clock support on i.MX
- A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and
clk-pllv3 drivers
- Drop dependency on ARM64 for i.MX8M clock driver, to support
aarch32 mode on aarch64 hardware
- A series from Peng Fan to improve i.MX8M clock drivers, using
composite clock for core and bus clk slice
- Set a better parent clock for flexcan on i.MX6UL to support CiA102
defined bit rates
- A couple changes for EMC frequency scaling on Tegra210
- Support for CPU frequency scaling on Tegra20/Tegra30
- New clk gate for CSI test pattern generator on Tegra210
- Regression fixes for Samsung exynos542x and exynos5433 SoCs
- Use of fallthrough; attribute for Samsung s3c24xx
- Updates and fixup HDMI and video clocks on Meson8b
- Fixup reset polarity on Meson8b
- Fix GPU glitch free mux switch on Meson gx and g12
- A minor fix for the currently unused suspend/resume handling on
Renesas RZ/A1 and RZ/A2
- Two more conversions of Renesas DT bindings to json-schema
- Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+"

f2fs-for-5.8-rc1
In this round, we've added some knobs to enhance compression feature and harden testing environment. In addition, we've fixed several bugs reported from Android devices such as long discarding latency, device hanging during quota_sync, etc. Enhancement: - support lzo-rle algorithm - add two ioctls to release and reserve blocks for compression - support partial truncation/fiemap on compressed file - introduce sysfs entries to attach IO flags explicitly - add iostat trace point along with read io stat Bug fix: - fix long discard latency - flush quota data by f2fs_quota_sync correctly - fix to recover parent inode number for power-cut recovery - fix lz4/zstd output buffer budget - parse checkpoint mount option correctly - avoid inifinite loop to wait for flushing node/meta pages - manage discard space correctly And some refactoring and clean up patches were added. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl7fojgACgkQQBSofoJI UNKaZQ//Rd6r7Z25SJkAoy+y/m6QDaKg4Ap1wR6+QmirR7HNxtpr3dXSVvmj4Xhu ZDJ3LHmerFiwR/X4zFPud+PAoBe3gJa2k7GT8q0g4YkgLy0hfX9PXt0t3I9F8vlk 8m34j+hQaL9/3FBK4/PSG541vR/UUnwvu6t2pJMnz7rgnLej5I6yOIaoaihz7m+i k0ofK5ckuTNcZReAZ2tCIehQku7tDOBLdS5KxvBZBgRh0i5iSXXIa4ddvaMJdT/M WcjTZ6N8bFu0hCZ5hz9dyGGYo1XchQosLdLGhcEugsyxNp9Yuftyf5/Ie1wJNiEl ZsoRc15X7wfRPKKMMyDFljzPBPFiHr78p30uJ34bcYCu0j0CYi+gbKQztmEMZ2dy 9M+sDG3jd5R7ACXrwS2ElSEDyLBnTaxbeSdCpErGjn/U19TLllbzhnMA9KR9elDI pEWgRc7DPmPbRZaStXMxIamf7pbmUSm0akAYbzGFvMHcSx4MXuQFICGK9t/mhSDm sO2b1Ir39yk65sVNdjFsnqDsi6jTPgrLSe3FY4eMhkn15OSiVGhcz7ddQMD7Fbuq WLpHFqER650I28i0EXh8bxzjkrj+aJQKhGcVbmwVS33MtKVfBdh4GfQMvS6MbeOM MsZ10E7Dr9ildKxqHP5SgLlggkl512lpj3+d6j0mUSSSUP2jtUw= =MiEC -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added some knobs to enhance compression feature and harden testing environment.

Tracing updates for 5.8:
No new features this release. Mostly clean ups, restructuring and
documentation.
- Have ftrace_bug() show ftrace errors before the WARN, as the WARN will
reboot the box before the error messages are printed if panic_on_warn
is set.
- Have traceoff_on_warn disable tracing sooner (before prints)
- Write a message to the trace buffer that its being disabled when
disable_trace_on_warning() is set.
- Separate out synthetic events from histogram code to let it be used by
other parts of the kernel.
- More documentation on histogram design.
- Other small fixes and clean ups.

Merge branch 'x86/srbds' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 srbds fixes from Thomas Gleixner:
"The 9th episode of the dime novel "The performance killer" with the
subtitle "Slow Randomizing Boosts Denial of Service".
SRBDS is an MDS-like speculative side channel that can leak bits from
the random number generator (RNG) across cores and threads. New
microcode serializes the processor access during the execution of
RDRAND and RDSEED. This ensures that the shared buffer is overwritten
before it is released for reuse. This is equivalent to a full bus
lock, which means that many threads running the RNG instructions in
parallel have the same effect as the same amount of threads issuing a
locked instruction targeting an address which requires locking of two
cachelines at once.
The mitigation support comes with the usual pile of unpleasant
ingredients:
- command line options
- sysfs file
- microcode checks
- a list of vulnerable CPUs identified by model and stepping this
time which requires stepping match support for the cpu match logic.
- the inevitable slowdown of affected CPUs"

remoteproc updates for v5.8
This introduces device managed versions of functions used to register remoteproc devices, add support for remoteproc driver specific resource control, enables remoteproc drivers to specify ELF class and machine for coredumps. It integrates pm_runtime in the core for keeping resources active while the remote is booted and holds a wake source while recoverying a remote processor after a firmware crash. It refactors the remoteproc device's allocation path to simplify the logic, fix a few cleanup bugs and to not clone const strings onto the heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a zero-length array is replaced with flexible-array. A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm SM8250 gains support for audio, compute and sensor remoteprocs and the Qualcomm SC7180 modem support is cleaned up and improved. The Qualcomm glink subsystem-restart driver is merged into the main glink driver, the Qualcomm sysmon driver is extended to properly notify remote processors about all other remote processors' state transitions. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl7egk0bHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FQnwQAM781m7BqSKdtbH0OzGB K4jGX/IkWCEluXx/RuDbPFV0mx/yLOfsrSzBBYnnTl+CXTgSLFtImRvwx5BFbnAl bRNbSlw1GLiV/w+HceIx1iKTELnkHKp4TT3zUmR+dZ+7pT1dhWXzHIjyjJPC1c7R L8qg3qlOrM620y3OJNUo57/20Tg9WN6kBKdaeyJKjmBsENrw6wggY30ijqhMgCYr 9LgStPjtuSGgf4j55+BeTskVSnOvuun5NlVpRUVTo+ZDKTZAyO/8TKM+yWffAHc5 7WkK0z9E3lhwdNPLif+dSIvhLjiyKR2yJf5KP7n9mFhA1tRVqNXnJqMCnAnwVvzT IpL1INYbirRwPfayhCsUSwKDTKkckKP9I/vZ7WKWJD9SWcc4eGWIifNDNGkMQ6qV 7S0+6AyCANBltRPKTl6zwXSrrHuBUNkH3r9gddT5tPJu7Klh+fjKEywpsXkUd+IY Xo1nuT+mYrUgif0KTh656EK6YM5dFuVnZqOszzgiVUrdKeHKYBsUjWD7vS7DBeLe pLiDfo0qMb/J0sPptMt+0Rg/b/Nt1YiddW3ZlnVmWRCRjIQRJt9LQZcQoVhVv1Sa OQkhlvFTqIEFJfLtvp83zvL5WngxVM5Dq6mDiesAjZUhyode9ZtOGxr9zyhA4ApU njqp4n16OxcXaqjwp+k6eK8L =4k54 -----END PGP SIGNATURE----- Merge tag 'rproc-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This introduces device managed versions of functions used to register remoteproc devices, add support for remoteproc driver specific resource control, enables remoteproc drivers to specify ELF class and machine for coredumps.
