There are some new broken doc links due to yaml renames
at DT. Developers should really run:

in order to solve those issues while submitting patches.
This tool can even fix most of the issues with:

Vaibhav Jain b791abf320 powerpc/papr_scm: Fetch nvdimm health information from PHYP
Implement support for fetching nvdimm health information via
H_SCM_HEALTH hcall as documented in Ref[1]. The hcall returns a pair
of 64-bit bitmap, bitwise-and of which is then stored in
'struct papr_scm_priv' and subsequently partially exposed to
user-space via newly introduced dimm specific attribute
'papr/flags'. Since the hcall is costly, the health information is
cached and only re-queried, 60s after the previous successful hcall.

The patch also adds a  documentation text describing flags reported by
the the new sysfs attribute 'papr/flags' is also introduced at
Documentation/ABI/testing/sysfs-bus-papr-pmem.

Dave Martin 9ba6a9efa4 docs/arm64: Fix typo'd #define in sve.rst
sve.rst describes a flag PR_SVE_SET_VL_INHERIT for the
PR_SVE_SET_VL prctl, but there is no flag of this name.  The flag
is shared between the _GET and _SET calls, so the _SET prefix was
dropped, giving the name PR_SVE_VL_INHERIT in the headers.

Fix it.

 "I2C has quite some patches for you this time. I hope it is the move to

  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. I chose to apply them right
  away because they were trivial"

  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.

    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.

  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"

Linus Torvalds b791d1bdf9 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.

Dave Rodgman b5265c813c 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.

Rob Herring 0db958b689 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.

The easiest fix in most cases is to change the 'reg' property to 1 cell
for address and size.

Rob Herring c0eca14c57 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.

Rob Herring 086e9074f5 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.

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.h: Enforce that READ_ONCE_NOCHECK() access size is sizeof(long)
  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

Linus Torvalds 6f630784cc 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+

Conditional schema properties don't overwrite others. Instead of
restrictions have to be validated. So general clock amount is 1-2 and
depending on the actual device type limit the mount to 1 or 2.

Linus Torvalds 42612e7763 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.

Linus Torvalds d1e521adad 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.

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"

Linus Torvalds abfbb29297 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.

Starting from v4.19 commit 29ef680ae7 ("memcg, oom: move out_of_memory
back to the charge path") cgroup oom killer is no longer invoked only
from page faults.  Now it implements the same semantics as global OOM
killer: allocation context invokes OOM killer and keeps retrying until
success.

John Hubbard eaf4d22a9e docs: mm/gup: pin_user_pages.rst: add a "case 5"
Patch series "vhost, docs: convert to pin_user_pages(), new "case 5""

It recently became clear to me that there are some get_user_pages*()
callers that don't fit neatly into any of the four cases that are so far
listed in pin_user_pages.rst.  vhost.c is one of those.

Add a Case 5 to the documentation, and refer to that when converting
vhost.c.

Thanks to Jan Kara for helping me (again) in understanding the
interaction between get_user_pages() and page writeback [1].

This is based on today's mmotm, which has a nearby patch to
pin_user_pages.rst that rewords cases 3 and 4.

Note that I have only compile-tested the vhost.c patch, although that
does also include cross-compiling for a few other arches.  Any run-time
testing would be greatly appreciated.

[1] https://lore.kernel.org/r/20200529070343.GL14550@quack2.suse.cz

This patch (of 2):

There are four cases listed in pin_user_pages.rst.  These are intended
to help developers figure out whether to use get_user_pages*(), or
pin_user_pages*().  However, the four cases do not cover all the
situations.  For example, drivers/vhost/vhost.c has a "pin, write to
page, set page dirty, unpin" case.

Add a fifth case, to help explain that there is a general pattern that
requires pin_user_pages*() API calls.

Guilherme G. Piccoli 60c958d8df panic: add sysctl to dump all CPUs backtraces on oops event
Usually when the kernel reaches an oops condition, it's a point of no
return; in case not enough debug information is available in the kernel
splat, one of the last resorts would be to collect a kernel crash dump
and analyze it.  The problem with this approach is that in order to
collect the dump, a panic is required (to kexec-load the crash kernel).
When in an environment of multiple virtual machines, users may prefer to
try living with the oops, at least until being able to properly shutdown
their VMs / finish their important tasks.

This patch implements a way to collect a bit more debug details when an
oops event is reached, by printing all the CPUs backtraces through the
usage of NMIs (on architectures that support that).  The sysctl added
(and documented) here was called "oops_all_cpu_backtrace", and when set
will (as the name suggests) dump all CPUs backtraces.

Far from ideal, this may be the last option though for users that for
some reason cannot panic on oops.  Most of times oopses are clear enough
to indicate the kernel portion that must be investigated, but in virtual
environments it's possible to observe hypervisor/KVM issues that could
lead to oopses shown in other guests CPUs (like virtual APIC crashes).
This patch hence aims to help debug such complex issues without
resorting to kdump.

Guilherme G. Piccoli 0ec9dc9bcb kernel/hung_task.c: introduce sysctl to print all traces when a hung task is detected
Commit 401c636a0e ("kernel/hung_task.c: show all hung tasks before
panic") introduced a change in that we started to show all CPUs
backtraces when a hung task is detected _and_ the sysctl/kernel
parameter "hung_task_panic" is set.  The idea is good, because usually
when observing deadlocks (that may lead to hung tasks), the culprit is
another task holding a lock and not necessarily the task detected as
hung.

The problem with this approach is that dumping backtraces is a slightly
expensive task, specially printing that on console (and specially in
many CPU machines, as servers commonly found nowadays).  So, users that
plan to collect a kdump to investigate the hung tasks and narrow down
the deadlock definitely don't need the CPUs backtrace on dmesg/console,
which will delay the panic and pollute the log (crash tool would easily
grab all CPUs traces with 'bt -a' command).

Also, there's the reciprocal scenario: some users may be interested in
seeing the CPUs backtraces but not have the system panic when a hung
task is detected.  The current approach hence is almost as embedding a
policy in the kernel, by forcing the CPUs backtraces' dump (only) on
hung_task_panic.

This patch decouples the panic event on hung task from the CPUs
backtraces dump, by creating (and documenting) a new sysctl called
"hung_task_all_cpu_backtrace", analog to the approach taken on soft/hard
lockups, that have both a panic and an "all_cpu_backtrace" sysctl to
allow individual control.  The new mechanism for dumping the CPUs
backtraces on hung task detection respects "hung_task_warnings" by not
dumping the traces in case there's no warnings left.

Guilherme G. Piccoli f117955a22 kernel/watchdog.c: convert {soft/hard}lockup boot parameters to sysctl aliases
After a recent change introduced by Vlastimil's series [0], kernel is
able now to handle sysctl parameters on kernel command line; also, the
series introduced a simple infrastructure to convert legacy boot
parameters (that duplicate sysctls) into sysctl aliases.

This patch converts the watchdog parameters softlockup_panic and
{hard,soft}lockup_all_cpu_backtrace to use the new alias infrastructure.
It fixes the documentation too, since the alias only accepts values 0 or
1, not the full range of integers.

We also took the opportunity here to improve the documentation of the
previously converted hung_task_panic (see the patch series [0]) and put
the alias table in alphabetical order.

Vlastimil Babka b467f3ef3c kernel/hung_task convert hung_task_panic boot parameter to sysctl
We can now handle sysctl parameters on kernel command line and have
infrastructure to convert legacy command line options that duplicate
sysctl to become a sysctl alias.

This patch converts the hung_task_panic parameter.  Note that the sysctl
handler is more strict and allows only 0 and 1, while the legacy
parameter allowed any non-zero value.  But there is little reason anyone
would not be using 1.

Vlastimil Babka 3db978d480 kernel/sysctl: support setting sysctl parameters from kernel command line
Patch series "support setting sysctl parameters from kernel command line", v3.

This series adds support for something that seems like many people
always wanted but nobody added it yet, so here's the ability to set
sysctl parameters via kernel command line options in the form of
sysctl.vm.something=1

The important part is Patch 1.  The second, not so important part is an
attempt to clean up legacy one-off parameters that do the same thing as
a sysctl.  I don't want to remove them completely for compatibility
reasons, but with generic sysctl support the idea is to remove the
one-off param handlers and treat the parameters as aliases for the
sysctl variants.

I have identified several parameters that mention sysctl counterparts in
Documentation/admin-guide/kernel-parameters.txt but there might be more.
The conversion also has varying level of success:

 - numa_zonelist_order is converted in Patch 2 together with adding the
   necessary infrastructure. It's easy as it doesn't really do anything
   but warn on deprecated value these days.

 - hung_task_panic is converted in Patch 3, but there's a downside that
   now it only accepts 0 and 1, while previously it was any integer
   value

 - nmi_watchdog maps to two sysctls nmi_watchdog and hardlockup_panic,
   so there's no straighforward conversion possible

 - traceoff_on_warning is a flag without value and it would be required
   to handle that somehow in the conversion infractructure, which seems
   pointless for a single flag

This patch (of 5):

A recently proposed patch to add vm_swappiness command line parameter in
addition to existing sysctl [1] made me wonder why we don't have a
general support for passing sysctl parameters via command line.

Googling found only somebody else wondering the same [2], but I haven't
found any prior discussion with reasons why not to do this.

Settings the vm_swappiness issue aside (the underlying issue might be
solved in a different way), quick search of kernel-parameters.txt shows
there are already some that exist as both sysctl and kernel parameter -
hung_task_panic, nmi_watchdog, numa_zonelist_order, traceoff_on_warning.

A general mechanism would remove the need to add more of those one-offs
and might be handy in situations where configuration by e.g.
/etc/sysctl.d/ is impractical.

Hence, this patch adds a new parse_args() pass that looks for parameters
prefixed by 'sysctl.' and tries to interpret them as writes to the
corresponding sys/ files using an temporary in-kernel procfs mount.
This mechanism was suggested by Eric W.  Biederman [3], as it handles
all dynamically registered sysctl tables, even though we don't handle
modular sysctls.  Errors due to e.g.  invalid parameter name or value
are reported in the kernel log.

The processing is hooked right before the init process is loaded, as
some handlers might be more complicated than simple setters and might
need some subsystems to be initialized.  At the moment the init process
can be started and eventually execute a process writing to /proc/sys/
then it should be also fine to do that from the kernel.

Sysctls registered later on module load time are not set by this
mechanism - it's expected that in such scenarios, setting sysctl values
from userspace is practical enough.

Rafael Aquini db38d5c106 kernel: add panic_on_taint
Analogously to the introduction of panic_on_warn, this patch introduces
a kernel option named panic_on_taint in order to provide a simple and
generic way to stop execution and catch a coredump when the kernel gets
tainted by any given flag.

This is useful for debugging sessions as it avoids having to rebuild the
kernel to explicitly add calls to panic() into the code sites that
introduce the taint flags of interest.

For instance, if one is interested in proceeding with a post-mortem
analysis at the point a given code path is hitting a bad page (i.e.
unaccount_page_cache_page(), or slab_bug()), a coredump can be collected
by rebooting the kernel with 'panic_on_taint=0x20' amended to the
command line.

Another, perhaps less frequent, use for this option would be as a means
for assuring a security policy case where only a subset of taints, or no
single taint (in paranoid mode), is allowed for the running system.  The
optional switch 'nousertaint' is handy in this particular scenario, as
it will avoid userspace induced crashes by writes to sysctl interface
/proc/sys/kernel/tainted causing false positive hits for such policies.

Orson Zhai ceabef7dd7 dynamic_debug: add an option to enable dynamic debug for modules only
Instead of enabling dynamic debug globally with CONFIG_DYNAMIC_DEBUG,
CONFIG_DYNAMIC_DEBUG_CORE will only enable core function of dynamic
debug.  With the DYNAMIC_DEBUG_MODULE defined for any modules, dynamic
debug will be tied to them.

This is useful for people who only want to enable dynamic debug for
kernel modules without worrying about kernel image size and memory
consumption is increasing too much.

  Not all that huge this release, just a number of small fixes and
  updates:

   - software node fixes

   - kobject now sends KOBJ_REMOVE when it is removed from sysfs, not
     when it is removed from memory (which could come much later)

   - device link additions and fixes based on testing on more devices

   - firmware core cleanups

   - other minor changes, full details in the shortlog

  All have been in linux-next for a while with no reported issues"

Linus Torvalds 80ef846e99 Staging/IIO driver patches for 5.8-rc1
Here is the large set of staging and IIO driver changes for 5.8-rc1
 
 Nothing major, but a lot of new IIO drivers are included in here, along
 with other core iio cleanups and changes.
 
 On the staging driver front, again, nothing noticable.  No new deletions
 or additions, just a ton of tiny cleanups all over the tree done by a
 lot of different people.  Most coding style, but many actual real fixes
 and cleanups that are nice to see.
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds 081096d98b TTY/Serial driver updates for 5.8-rc1
Here is the tty and serial driver updates for 5.8-rc1
 
 Nothing huge at all, just a lot of little serial driver fixes, updates
 for new devices and features, and other small things.  Full details are
 in the shortlog.
 
 Note, you will get a conflict merging with your tree in the
 Documentation/devicetree/bindings/serial/rs485.yaml file, but it should
 be pretty obvious what to do.  If not, I'm sure Rob will clean it all up
 afterwards :)
 
 All of these have been in linux-next with no issues for a while.

Masahiro Yamada 269a535ca9 modpost: generate vmlinux.symvers and reuse it for the second modpost
The full build runs modpost twice, first for vmlinux.o and second for
modules.

The first pass dumps all the vmlinux symbols into Module.symvers, but
the second pass parses vmlinux again instead of reusing the dump file,
presumably because it needs to avoid accumulating stale symbols.

Loading symbol info from a dump file is faster than parsing an ELF object.
Besides, modpost deals with various issues to parse vmlinux in the second
pass.

A solution is to make the first pass dumps symbols into a separate file,
vmlinux.symvers. The second pass reads it, and parses module .o files.
The merged symbol information is dumped into Module.symvers in the same
way as before.

This makes further modpost cleanups possible.

Also, it fixes the problem of 'make vmlinux', which previously overwrote
Module.symvers, throwing away module symbols.

I slightly touched scripts/link-vmlinux.sh so that vmlinux is re-linked
when you cross this commit. Otherwise, vmlinux.symvers would not be
generated.

Linus Torvalds b25c6644bf - Largest change for this cycle is the DM zoned target's metadata
version 2 feature that adds support for pairing regular block
   devices with a zoned device to ease performance impact associated
   with finite random zones of zoned device.  Changes came in 3
   batches: first prepared for and then added the ability to pair a
   single regular block device, second was a batch of fixes to improve
   zoned's reclaim heuristic, third removed the limitation of only
   adding a single additional regular block device to allow many
   devices.  Testing has shown linear scaling as more devices are
   added.
 
 - Add new emulated block size (ebs) target that emulates a smaller
   logical_block_size than a block device supports.  Primary use-case
   is to emulate "512e" devices that have 512 byte logical_block_size
   and 4KB physical_block_size.  This is useful to some legacy
   applications otherwise wouldn't be ablee to be used on 4K devices
   because they depend on issuing IO in 512 byte granularity.
 
 - Add discard interfaces to DM bufio.  First consumer of the interface
   is the dm-ebs target that makes heavy use of dm-bufio.
 
 - Fix DM crypt's block queue_limits stacking to not truncate
   logic_block_size.
 
 - Add Documentation for DM integrity's status line.
 
 - Switch DMDEBUG from a compile time config option to instead use
   dynamic debug via pr_debug.
 
 - Fix DM multipath target's hueristic for how it manages
   "queue_if_no_path" state internally.  DM multipath now avoids
   disabling "queue_if_no_path" unless it is actually needed (e.g. in
   response to configure timeout or explicit "fail_if_no_path"
   message).  This fixes reports of spurious -EIO being reported back
   to userspace application during fault tolerance testing with an NVMe
   backend.  Added various dynamic DMDEBUG messages to assist with
   debugging queue_if_no_path in the future.
 
 - Add a new DM multipath "Historical Service Time" Path Selector.
 
 - Fix DM multipath's dm_blk_ioctl() to switch paths on IO error.
 
 - Improve DM writecache target performance by using explicit
   cache flushing for target's single-threaded usecase and a small

Linus Torvalds 3f7e82379f This is the bulk of GPIO changes for the v5.8 kernel cycle.
Core changes:
 
 - A new GPIO aggregator driver has been merged: this can
   join a few select GPIO lines into a new aggregated GPIO
   chip. This can be used for security: a process can be
   granted access to only these lines, for example for
   industrial control. Another way to use this is to
   reexpose certain select lines to a virtual machine or
   container.
 
 - Warn if the gpio-line-names is too long in he DT parser
   core.
 
 - GPIO lines can now be looked up by line name in addition
   to being looked up by offset.
 
 New drivers:
 
 - A new generic regmap GPIO driver has been merged. Too
   many regmap drivers are starting to look like each other
   so we need to create some common ground and try to move
   drivers over to using that.
 
 - The F7188X driver now supports F81865.
 
 Driver improvements:
 
 - Large improvements to the PCA953x expander, get multiple lines
   and several cleanups.
 
 - Large improvements to the DesignWare DWAPB driver, and Sergey
   Semin has volunteered to maintain it.
 
 - PL061 can now be built as a module, this is part of a bigger
   effort to make the ARM platforms more modular.

Linus Torvalds 7ae77150d9 powerpc updates for 5.8
- Support for userspace to send requests directly to the on-chip GZIP
    accelerator on Power9.
 
  - Rework of our lockless page table walking (__find_linux_pte()) to make it
    safe against parallel page table manipulations without relying on an IPI for
    serialisation.
 
  - A series of fixes & enhancements to make our machine check handling more
    robust.
 
  - Lots of plumbing to add support for "prefixed" (64-bit) instructions on
    Power10.
 
  - Support for using huge pages for the linear mapping on 8xx (32-bit).
 
  - Remove obsolete Xilinx PPC405/PPC440 support, and an associated sound driver.
 
  - Removal of some obsolete 40x platforms and associated cruft.
 
  - Initial support for booting on Power10.
 
  - Lots of other small features, cleanups & fixes.

Linus Torvalds 828f3e18e1 ARM/SoC: drivers for v5.7
These are updates to SoC specific drivers that did not have
 another subsystem maintainer tree to go through for some
 reason:
 
 - Some bus and memory drivers for the MIPS P5600 based
   Baikal-T1 SoC that is getting added through the MIPS tree.
 
 - There are new soc_device identification drivers for TI K3,
   Qualcomm MSM8939
 
 - New reset controller drivers for NXP i.MX8MP, Renesas
   RZ/G1H, and Hisilicon hi6220
 
 - The SCMI firmware interface can now work across ARM SMC/HVC
   as a transport.
 
 - Mediatek platforms now use a new driver for their "MMSYS"
   hardware block that controls clocks and some other aspects
   in behalf of the media and gpu drivers.
 
 - Some Tegra processors have improved power management
   support, including getting woken up by the PMIC and cluster
   power down during idle.
 
 - A new v4l staging driver for Tegra is added.
 
 - Cleanups and minor bugfixes for TI, NXP, Hisilicon,
   Mediatek, and Tegra.

Linus Torvalds 694b5a5d31 ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older
 Cortex-a7 based relative of the RTD12xx chips that are already supported
 in arch/arm64. The platform may also be extended to support running
 32-bit kernels on those 64-bit chips for memory-constrained machines.
 
 In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
 an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
 released in 2016 as one of the last high-end 32-bit designs.
 
 There is ongoing cleanup for the integrator, tegra, imx, and omap2
 platforms, with integrator getting very close to the goal of having
 zero code in arch/arm/, and omap2 moving more of the chip specifics
 from old board code into device tree files.
 
 The Versatile Express platform is made more modular, with built-in
 drivers now becoming loadable modules. This is part of a greater effort
 for the Android OS to have a common kernel binary for all platforms and
 any platform specific code in loadable modules.
 
 The PXA platform drops support for Compulab's pxa2xx boards that had
 rather unusual flash and PCI drivers but no known users remaining.
 All device drivers specific to those boards can now get removed as
 well.
 
 Across platforms, there is ongoing cleanup, with Geert and Rob
 revisiting some a lot of Kconfig options.

Anshuman Khandual 399145f9eb mm/debug: add tests validating architecture page table helpers
This adds tests which will validate architecture page table helpers and
other accessors in their compliance with expected generic MM semantics.
This will help various architectures in validating changes to existing
page table helpers or addition of new ones.

This test covers basic page table entry transformations including but not
limited to old, young, dirty, clean, write, write protect etc at various
level along with populating intermediate entries with next page table page
and validating them.

Test page table pages are allocated from system memory with required size
and alignments.  The mapped pfns at page table levels are derived from a
real pfn representing a valid kernel text symbol.  This test gets called
via late_initcall().

This test gets built and run when CONFIG_DEBUG_VM_PGTABLE is selected.
Any architecture, which is willing to subscribe this test will need to
select ARCH_HAS_DEBUG_VM_PGTABLE.  For now this is limited to arc, arm64,
x86, s390 and powerpc platforms where the test is known to build and run
successfully Going forward, other architectures too can subscribe the test
after fixing any build or runtime problems with their page table helpers.

Folks interested in making sure that a given platform's page table helpers
conform to expected generic MM semantics should enable the above config
which will just trigger this test during boot.  Any non conformity here
will be reported as an warning which would need to be fixed.  This test
will help catch any changes to the agreed upon semantics expected from
generic MM and enable platforms to accommodate it thereafter.

Andrey Konovalov 5ff3b30ab5 kcov: collect coverage from interrupts
This change extends kcov remote coverage support to allow collecting
coverage from soft interrupts in addition to kernel background threads.

To collect coverage from code that is executed in softirq context, a part
of that code has to be annotated with kcov_remote_start/stop() in a
similar way as how it is done for global kernel background threads.  Then
the handle used for the annotations has to be passed to the
KCOV_REMOTE_ENABLE ioctl.

Internally this patch adjusts the __sanitizer_cov_trace_pc() compiler
inserted callback to not bail out when called from softirq context.
kcov_remote_start/stop() are updated to save/restore the current per task
kcov state in a per-cpu area (in case the softirq came when the kernel was
already collecting coverage in task context).  Coverage from softirqs is
collected into pre-allocated per-cpu areas, whose size is controlled by
the new CONFIG_KCOV_IRQ_AREA_SIZE.

  I don't think I have exec sorted out enough to fix the issues I

   - trivial cleanups for exec

   - control flow simplifications

Pull proc updates from Eric Biederman:
 "This has four sets of changes:

   - modernize proc to support multiple private instances

   - ensure we see the exit of each process tid exactly

   - remove has_group_leader_pid

   - use pids not tasks in posix-cpu-timers lookup

  Alexey updated proc so each mount of proc uses a new superblock. This
  allows people to actually use mount options with proc with no fear of
  messing up another mount of proc. Given the kernel's internal mounts
  of proc for things like uml this was a real problem, and resulted in
  Android's hidepid mount options being ignored and introducing security
  issues.

  The rest of the changes are small cleanups and fixes that came out of
  my work to allow this change to proc. In essence it is swapping the
  pids in de_thread during exec which removes a special case the code
  had to handle. Then updating the code to stop handling that special
  case"

Miklos Szeredi df820f8de4 ovl: make private mounts longterm
Overlayfs is using clone_private_mount() to create internal mounts for
underlying layers.  These are used for operations requiring a path, such as
dentry_open().

Since these private mounts are not in any namespace they are treated as
short term, "detached" mounts and mntput() involves taking the global
mount_lock, which can result in serious cacheline pingpong.

Make these private mounts longterm instead, which trade the penalty on
mntput() for a slightly longer shutdown time due to an added RCU grace
period when putting these mounts.

Introduce a new helper kern_unmount_many() that can take care of multiple
longterm mounts with a single RCU grace period.

   userspace-api books (a longstanding request from Jon);

 - The media Kconfig was reorganized, in order to make easier to select
   drivers and their dependencies;

 - The testing drivers now has a separate directory;

 - added a new driver for Rockchip Video Decoder IP;

 - The atomisp staging driver was resurrected. It is meant to work with
   4 generations of cameras on Atom-based laptops, tablets and cell
   phones. So, it seems worth investing time to cleanup this driver and
   making it in good shape.

 - Added some V4L2 core ancillary routines to help with h264 codecs;

 - Added an ov2740 image sensor driver;

 - The si2157 gained support for Analog TV, which, in turn, added
   support for some cx231xx and cx23885 boards to also support analog
   standards;

 - Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
   V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
   is located at the device;

 - VIDIOC_ENUM_FMT was extended to support MC-centric devices;

 - Lots of drivers improvements and cleanups.

Christoph Hellwig cddf8a2c4a fs: move fiemap range validation into the file systems instances
Replace fiemap_check_flags with a fiemap_prep helper that also takes the
inode and mapped range, and performs the sanity check and truncation
previously done in fiemap_check_range.  This way the validation is inside
the file system itself and thus properly works for the stacked overlayfs
case as well.

Johannes Weiner c843966c55 mm: allow swappiness that prefers reclaiming anon over the file workingset
With the advent of fast random IO devices (SSDs, PMEM) and in-memory swap
devices such as zswap, it's possible for swap to be much faster than
filesystems, and for swapping to be preferable over thrashing filesystem
caches.

Allow setting swappiness - which defines the rough relative IO cost of
cache misses between page cache and swap-backed pages - to reflect such
situations by making the swap-preferred range configurable.

Mike Kravetz 282f421438 hugetlbfs: clean up command line processing
With all hugetlb page processing done in a single file clean up code.

- Make code match desired semantics
  - Update documentation with semantics
- Make all warnings and errors messages start with 'HugeTLB:'.
- Consistently name command line parsing routines.
- Warn if !hugepages_supported() and command line parameters have
  been specified.
- Add comments to code
  - Describe some of the subtle interactions
  - Describe semantics of command line arguments

This patch also fixes issues with implicitly setting the number of
gigantic huge pages to preallocate.  Previously on X86 command line,

        hugepages=2 default_hugepagesz=1G

would result in zero 1G pages being preallocated and,

        # grep HugePages_Total /proc/meminfo
        HugePages_Total:       0
        # sysctl -a | grep nr_hugepages
        vm.nr_hugepages = 2
        vm.nr_hugepages_mempolicy = 2
        # cat /proc/sys/vm/nr_hugepages
        2

After this patch 2 gigantic pages will be preallocated and all the proc,
sysfs, sysctl and meminfo files will accurately reflect this.

To address the issue with gigantic pages, a small change in behavior was
made to command line processing.  Previously the command line,

        hugepages=128 default_hugepagesz=2M hugepagesz=2M hugepages=256

would result in the allocation of 256 2M huge pages.  The value 128 would
be ignored without any warning.  After this patch, 128 2M pages will be
allocated and a warning message will be displayed indicating the value of
256 is ignored.  This change in behavior is required because allocation of
implicitly specified gigantic pages must be done when the
default_hugepagesz= is encountered for gigantic pages.  Previously the
code waited until later in the boot process (hugetlb_init), to allocate
pages of default size.  However the bootmem allocator required for
gigantic allocations is not available at this time.

Kirill A. Shutemov 71a2c112a0 khugepaged: introduce 'max_ptes_shared' tunable
'max_ptes_shared' specifies how many pages can be shared across multiple
processes.  Exceeding the number would block the collapse::

	/sys/kernel/mm/transparent_hugepage/khugepaged/max_ptes_shared

A higher value may increase memory footprint for some workloads.

By default, at least half of pages has to be not shared.

Mike Rapoport 3f08a302f5 mm: remove CONFIG_HAVE_MEMBLOCK_NODE_MAP option
CONFIG_HAVE_MEMBLOCK_NODE_MAP is used to differentiate initialization of
nodes and zones structures between the systems that have region to node
mapping in memblock and those that don't.

Currently all the NUMA architectures enable this option and for the
non-NUMA systems we can presume that all the memory belongs to node 0 and
therefore the compile time configuration option is not required.

The remaining few architectures that use DISCONTIGMEM without NUMA are
easily updated to use memblock_add_node() instead of memblock_add() and
thus have proper correspondence of memblock regions to NUMA nodes.

Still, free_area_init_node() must have a backward compatible version
because its semantics with and without CONFIG_HAVE_MEMBLOCK_NODE_MAP is
different.  Once all the architectures will use the new semantics, the
entire compatibility layer can be dropped.

To avoid addition of extra run time memory to store node id for
architectures that keep memblock but have only a single node, the node id
field of the memblock_region is guarded by CONFIG_NEED_MULTIPLE_NODES and
the corresponding accessors presume that in those cases it is always 0.

Linus Torvalds f1e455352b kgdb patches for 5.8-rc1
By far the biggest change in this cycle are the changes that allow much
 earlier debug of systems that are hooked up via UART by taking advantage
 of the earlycon framework to implement the kgdb I/O hooks before handing
 over to the regular polling I/O drivers once they are available. When
 discussing Doug's work we also found and fixed an broken
 raw_smp_processor_id() sequence in in_dbg_master().
 
 Also included are a collection of much smaller fixes and tweaks: a
 couple of tweaks to ged rid of doc gen or coccicheck warnings, future
 proof some internal calculations that made implicit power-of-2
 assumptions and eliminate some rather weird handling of magic
 environment variables in kdb.

Linus Torvalds f6aee505c7 X86 timer specific updates:
- Add TPAUSE based delay which allows the CPU to enter an optimized power
    state while waiting for the delay to pass. The delay is based on TSC
    cycles.
 
  - Add tsc_early_khz command line parameter to workaround the problem that
    overclocked CPUs can report the wrong frequency via CPUID.16h which
    causes the refined calibration to fail because the delta to the initial
    frequency value is too big. With the parameter users can provide an
    halfways accurate initial value.
