Pull thermal control updates from Rafael Wysocki:
"The majority of changes here are related to the general switch-over to
using arrays of generic trip point structures registered along with a
thermal zone instead of trip point callbacks (this has been done
mostly by Daniel Lezcano with some help from yours truly on the Intel
drivers front).
Apart from that and the related reorganization of code, there are some
enhancements of the existing driver and a new Mediatek Low Voltage
Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
rework so it will use the generic idle_inject facility for CPU idle
time injection going forward and it will take additional module
parameters for specifying the subset of CPUs to be affected by it
(work done by Srinivas Pandruvada).
Also included are assorted fixes and a whole bunch of cleanups.
Specifics:
- Rework a large bunch of drivers to use the generic thermal trip
structure and use the opportunity to do more cleanups by removing
unused functions from the OF code (Daniel Lezcano)
- Remove core header inclusion from drivers (Daniel Lezcano)
- Fix some locking issues related to the generic thermal trip rework
(Johan Hovold)
- Fix a crash when requesting the critical temperature on tegra,
which is related to the generic trip point work (Jon Hunter)
- Clean up thermal device unregistration code (Viresh Kumar)
- Fix and clean up thermal control core initialization error code
paths (Daniel Lezcano)
- Relocate the trip points handling code into a separate file (Daniel
Lezcano)
- Make the thermal core fail registration of thermal zones and
cooling devices if the thermal class has not been registered
(Rafael Wysocki)
- Add trip point initialization helper functions for ACPI-defined
trip points and modify two thermal drivers to use them (Rafael
Wysocki, Daniel Lezcano)
- Make the core thermal control code use sysfs_emit_at() instead of
scnprintf() where applicable (ye xingchen)
- Consolidate code accessing the Intel TCC (Thermal Control
Circuitry) MSRs by introducing library functions for that and
making the TCC-related code in thermal drivers use them (Zhang Rui)
- Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
changes (Zhang Rui)
- Address an "unsigned expression compared with zero" warning in the
intel_soc_dts_iosf thermal driver (Yang Li)
- Update comments regarding two functions in the Intel Menlow thermal
driver (Deming Wang)
- Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
driver (ye xingchen)
- Make the intel_pch thermal driver support the Wellsburg PCH (Tim
Zimmermann)
- Modify the intel_pch and processor_thermal_device_pci thermal
drivers use generic trip point tables instead of thermal zone trip
point callbacks (Daniel Lezcano)
- Add production mode attribute sysfs attribute to the int340x
thermal driver (Srinivas Pandruvada)
- Rework dynamic trip point updates handling and locking in the
int340x thermal driver (Rafael Wysocki)
- Make the int340x thermal driver use a generic trip points table
instead of thermal zone trip point callbacks (Rafael Wysocki,
Daniel Lezcano)
- Clean up and improve the int340x thermal driver (Rafael Wysocki)
- Simplify and clean up the intel_pch thermal driver (Rafael Wysocki)
- Fix the Intel powerclamp thermal driver and make it use the common
idle injection framework (Srinivas Pandruvada)
- Add two module parameters, cpumask and max_idle, to the Intel
powerclamp thermal driver to allow it to affect only a specific
subset of CPUs instead of all of them (Srinivas Pandruvada)
- Make the Intel quark_dts thermal driver Use generic trip point
objects instead of its own trip point representation (Daniel
Lezcano)
- Add toctree entry for thermal documents and fix two issues in the
Intel powerclamp driver documentation (Bagas Sanjaya)
- Use strscpy() to instead of strncpy() in the thermal core (Xu
Panda)
- Fix thermal_sampling_exit() (Vincent Guittot)
- Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam
Chihi)
- Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert
Uytterhoeven)
- Fix useless call to set_trips() when resuming in the rcar_gen3
thermal control driver and add interrupt support detection at init
time to it (Niklas Söderlund)
- Fix memory corruption in the hi3660 thermal driver (Yongqin Liu)
- Fix include path for libnl3 in pkg-config file for libthermal
(Vibhav Pant)

Pull RCU updates from Paul McKenney:
- Documentation updates
- Miscellaneous fixes, perhaps most notably:
- Throttling callback invocation based on the number of callbacks
that are now ready to invoke instead of on the total number of
callbacks
- Several patches that suppress false-positive boot-time
diagnostics, for example, due to lockdep not yet being
initialized
- Make expedited RCU CPU stall warnings dump stacks of any tasks
that are blocking the stalled grace period. (Normal RCU CPU
stall warnings have done this for many years)
- Lazy-callback fixes to avoid delays during boot, suspend, and
resume. (Note that lazy callbacks must be explicitly enabled, so
this should not (yet) affect production use cases)
- Make kfree_rcu() and friends take advantage of polled grace periods,
thus reducing memory footprint by almost two orders of magnitude,
admittedly on a microbenchmark
This also begins the transition from kfree_rcu(p) to
kfree_rcu_mightsleep(p). This transition was motivated by bugs where
kfree_rcu(p), which can block, was typed instead of the intended
kfree_rcu(p, rh)
- SRCU updates, perhaps most notably fixing a bug that causes SRCU to
fail when booted on a system with a non-zero boot CPU. This
surprising situation actually happens for kdump kernels on the
powerpc architecture
This also adds an srcu_down_read() and srcu_up_read(), which act like
srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side
critical section to be handed off from one task to another
- Clean up the now-useless SRCU Kconfig option
There are a few more commits that are not yet acked or pulled into
maintainer trees, and these will be in a pull request for a later
merge window
- RCU-tasks updates, perhaps most notably these fixes:
- A strange interaction between PID-namespace unshare and the
RCU-tasks grace period that results in a low-probability but
very real hang
- A race between an RCU tasks rude grace period on a single-CPU
system and CPU-hotplug addition of the second CPU that can
result in a too-short grace period
- A race between shrinking RCU tasks down to a single callback
list and queuing a new callback to some other CPU, but where
that queuing is delayed for more than an RCU grace period. This
can result in that callback being stranded on the non-boot CPU
- Torture-test updates and fixes
- Torture-test scripting updates and fixes
- Provide additional RCU CPU stall-warning information in kernels built
with CONFIG_RCU_CPU_STALL_CPUTIME=y, and restore the full five-minute
timeout limit for expedited RCU CPU stall warnings

When devlink instance is put into network namespace and that network
namespace gets deleted, devlink instance is moved back into init_ns.
This is done as a part of cleanup_net() routine. Since cleanup_net()
is called asynchronously from workqueue, there is no guarantee that
the devlink instance move is done after "ip netns del" returns.
So fix this race by making sure that the devlink instance is present
before any other operation.

Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,
leading to a chain of failures.
A simple fix is to always call cleanup function when the script exists.
This approach is already used by other existing tests.

There are scenes that we want to show the character value of traced
arguments other than a decimal or hexadecimal or string value for debug
convinience. I add a new type named 'char' to do it and a new test case
file named 'kprobe_args_char.tc' to do selftest for char type.
For example:
The to be traced function is 'void demo_func(char type, char *name);', we
can add a kprobe event as follows to show argument values as we want:
echo 'p:myprobe demo_func $arg1:char +0($arg2):char[5]' > kprobe_events
we will get the following trace log:
... myprobe: (demo_func+0x0/0x29) arg1='A' arg2={'b','p','f','1',''}

Fix kprobe probepoint testcase to ignore __pfx_* prefix symbols. Those are
introduced by commit b341b20d648b ("x86: Add prefix symbols for function

A lot of the tsan helpers are already excempt from the UACCESS warnings,
but some more functions were added that need the same thing:
kernel/kcsan/core.o: warning: objtool: __tsan_volatile_read16+0x0: call to __tsan_unaligned_read16() with UACCESS enabled
kernel/kcsan/core.o: warning: objtool: __tsan_volatile_write16+0x0: call to __tsan_unaligned_write16() with UACCESS enabled

vmlinux.o: warning: objtool: __tsan_unaligned_volatile_write16+0x4: call to __tsan_unaligned_write16() with UACCESS enabled
As Marco points out, these functions don't even call each other
explicitly but instead gcc (but not clang) notices the functions
being identical and turns one symbol into a direct branch to the
other.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping
Pull vfs idmapping updates from Christian Brauner:
- Last cycle we introduced the dedicated struct mnt_idmap type for
mount idmapping and the required infrastucture in 256c8aed2b42 ("fs:
introduce dedicated idmap type for mounts"). As promised in last
cycle's pull request message this converts everything to rely on
struct mnt_idmap.
Currently we still pass around the plain namespace that was attached
to a mount. This is in general pretty convenient but it makes it easy
to conflate namespaces that are relevant on the filesystem with
namespaces that are relevant on the mount level. Especially for
non-vfs developers without detailed knowledge in this area this was a
potential source for bugs.
This finishes the conversion. Instead of passing the plain namespace
around this updates all places that currently take a pointer to a
mnt_userns with a pointer to struct mnt_idmap.
Now that the conversion is done all helpers down to the really
low-level helpers only accept a struct mnt_idmap argument instead of
two namespace arguments.
Conflating mount and other idmappings will now cause the compiler to
complain loudly thus eliminating the possibility of any bugs. This
makes it impossible for filesystem developers to mix up mount and
filesystem idmappings as they are two distinct types and require
distinct helpers that cannot be used interchangeably.
Everything associated with struct mnt_idmap is moved into a single
separate file. With that change no code can poke around in struct
mnt_idmap. It can only be interacted with through dedicated helpers.
That means all filesystems are and all of the vfs is completely
oblivious to the actual implementation of idmappings.
We are now also able to extend struct mnt_idmap as we see fit. For
example, we can decouple it completely from namespaces for users that
don't require or don't want to use them at all. We can also extend
the concept of idmappings so we can cover filesystem specific
requirements.
In combination with the vfs{g,u}id_t work we finished in v6.2 this
makes this feature substantially more robust and thus difficult to
implement wrong by a given filesystem and also protects the vfs.
- Enable idmapped mounts for tmpfs and fulfill a longstanding request.
A long-standing request from users had been to make it possible to
create idmapped mounts for tmpfs. For example, to share the host's
tmpfs mount between multiple sandboxes. This is a prerequisite for
some advanced Kubernetes cases. Systemd also has a range of use-cases
to increase service isolation. And there are more users of this.
However, with all of the other work going on this was way down on the
priority list but luckily someone other than ourselves picked this
up.
As usual the patch is tiny as all the infrastructure work had been
done multiple kernel releases ago. In addition to all the tests that
we already have I requested that Rodrigo add a dedicated tmpfs
testsuite for idmapped mounts to xfstests. It is to be included into
xfstests during the v6.3 development cycle. This should add a slew of
additional tests.

There is a disconnect between the run_command function and the
wait_for_input. The wait_for_input has a default timeout of 2 minutes. But
if that happens, the run_command loop will exit out to the waitpid() of
the executing command. This fails in that it no longer monitors the
command, and also, the ssh to the test box can hang when its finished, as
it's waiting for the pipe it's writing to to flush, but the loop that
reads that pipe has already exited, leaving the command stuck, and the
test hangs.
Instead, make the default "wait_for_input" of the run_command infinite,
and allow the user to override it if they want with a default timeout
option "RUN_TIMEOUT".
But this fixes the hang that happens when the pipe is full and the ssh
session never exits.

so. If Ctrl^C is hit during this mode, the stdout is not back to the

In the "reboot" command, it does a check of the machine to see if it is
still alive with a simple "ssh echo" command. If it fails, it will assume
that a normal "ssh reboot" is not possible and force a power cycle.
In this case, the "start_monitor" is executed, but the "end_monitor" is
not, and this causes the screen will not be given back to the console. That
is, after the test, a "reset" command needs to be performed, as "echo" is
turned off.

KVM/arm64 updates for 6.3
- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place.
- Add support for taking stage-2 access faults in parallel. This was an
accidental omission in the original parallel faults implementation,
but should provide a marginal improvement to machines w/o FEAT_HAFDBS
(such as hardware from the fruit company).
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception handling
and masking unsupported features for nested guests.
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM.
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at reducing
the trap overhead of running nested.
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems.
- Avoid VM-wide stop-the-world operations when a vCPU accesses its own
redistributor.
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
in the host.
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer
This also drags in arm64's 'for-next/sme2' branch, because both it and
the PSCI relay changes touch the EL2 initialization code.

Data passed to user-space with a (SOL_UDP, UDP_GRO) cmsg carries an
int (see udp_cmsg_recv), not a u16 value, as strace confirms:
recvmsg(8, {msg_name=...,
msg_iov=[{iov_base="\0\0..."..., iov_len=96000}],
msg_iovlen=1,
msg_control=[{cmsg_len=20, <-- sizeof(cmsghdr) + 4
cmsg_level=SOL_UDP,
cmsg_type=0x68}], <-- UDP_GRO
msg_controllen=24,
msg_flags=0}, 0) = 11200
Interpreting the data as an u16 value won't work on big-endian platforms.
Since it is too late to back out of this API decision [1], fix the test.

Switch the hard coded metrics to use the aggregate value rather than
from saved_value. When computing a metric like IPC the aggregate count
comes from instructions then cycles is looked up and if present IPC
computed. Rather than lookup from the saved_value rbtree, search the
counter's evlist for the desired counter.
A new helper evsel__stat_type is used to both quickly find a metric
function and to identify when a counter is the one being sought. So
that both total and miss counts can be sought, the stat_type enum is
expanded. The ratio functions are rewritten to share a common helper
with the ratios being directly passed rather than computed from an
enum value.

Request the topdown metric group of a level with the metrics in the
group 'TopdownL<level>' rather than through specific events. As more
topdown levels are supported this way, such as 6 on Intel Ice Lake,
default to just showing the level 1 metrics. This can be overridden
using '--td-level'. Rather than determine the maximum topdown level
from sysfs, use the metric group names. Remove some now unused topdown
code.

When there are no events and on Intel, the topdown events will be
added by default if present. To display the metrics associated with
these request special handling in stat-shadow.c. To more easily update
these metrics use the json metric version via the TopdownL1
group. This makes the handling less platform specific.
Modify the metricgroup__has_metric code to also cover metric groups.

Thresholds may need additional events, this can impact things like
sharing groups of events to avoid multiplexing. Add a flag to make the
threshold calculations optional. The threshold will still be computed
if no additional events are necessary.

Comparison and logical operations on NAN won't ensure the result is
NAN. Ensure NANs are propogated so that threshold expressions like
"tma_fetch_latency > 0.1 & tma_frontend_bound > 0.15" don't yield a
number when the components are NAN.

Compute the threshold metric and use it to color the metric value as
red or green. The threshold expression is used to generate the set of
events as the threshold may require additional events. A later patch
