Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

ASoC: Fixes for v6.12

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

Merge tag 'i2c-host-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow

The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.

The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.

Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.

Follows the list of the rest of the changes grouped by type of
change.

Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.

The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.

The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.

Constified a few global data structures in the virtio driver.

The Renesas driver simplifies the bus speed handling in the init
function making it more readable.

Improved an if/else statement in probe function of the Renesas
R-Car driver.

The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().

Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.

Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.

Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.

Improvements
------------
The Renesas I2C (riic) driver undergoes several patches improving
the runtime power management handling.

The Intel i801 driver uses a more descriptive adapter's name to
show the presence of the IDF feature.

In the Intel Denverton (ismt) adapter the pending transactions
are killed when irq's can't complete their handling, triggering a
timeout. This could have been considered as a bug fix, but
because, standing to Vasily, it's very sporadic, I preferred
considering the patch rather as an improvement.

New Feature
-----------
The Renesas I2C (riic) driver now supports the fast mode plus.

New support
-----------
Added support for:

- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.

The Keba comes with a new driver, i2c-keba.c.
The Mule is an i2c multiplexer and it also comes with a new
driver, mux/i2c-mux-mule.c.

Core patch
----------
This pull request includes also a patch in the I2C framework, in
i2c-core-base.c where the runtime PM functions have been replaced
in order to allow to be accessed during the device add.

Devicetree
----------
Some cleanups in the devicetree, as well. nVidia and Qualcomm
bindings improve their "if:then:" blocks. While the aspeed
binding loses the "multi-master" property because it was
redundant.

The i2c-sprd binding has been converted to YAML.

Pull perf tools updates from Arnaldo Carvalho de Melo:

- Use BPF + BTF to collect and pretty print syscall and tracepoint
arguments in 'perf trace', done as an GSoC activity

- Data-type profiling improvements:

- Cache debuginfo to speed up data type resolution

- Add the 'typecln' sort order, to show which cacheline in a target
is hot or cold. The following shows members in the cfs_rq's first
cache line:

$ perf report -s type,typecln,typeoff -H
...
- 2.67% struct cfs_rq

0.39% struct cfs_rq +0x14 (h_nr_running)
0.02% struct cfs_rq +0x38 (tasks_timeline.rb_leftmost)

- When a typedef resolves to a unnamed struct, use the typedef name

- When a struct has just one basic type field (int, etc), resolve
the type sort order to the name of the struct, not the type of
the field

- Support type folding/unfolding in the data-type annotation TUI

- Fix bitfields offsets and sizes

- Initial support for PowerPC, using libcapstone and the usual
objdump disassembly parsing routines

- Add support for disassembling and addr2line using the LLVM libraries,
speeding up those operations

- Support --addr2line option in 'perf script' as with other tools

- Intel branch counters (LBR event logging) support, only available in
recent Intel processors, for instance, the new "brcntr" field can be
asked from 'perf script' to print the information collected from this
feature:

$ perf script -F +brstackinsn,+brcntr

- Support Timed PEBS (Precise Event-Based Sampling), a recent hardware
feature in Intel processors

- Add 'perf ftrace profile' subcommand, using ftrace's function-graph
tracer so that users can see the total, average, max execution time
as well as the number of invocations easily, for instance:

- 'perf sched timehist' improvements, including the addition of
priority showing/filtering command line options

- Varios improvements to the 'perf probe', including 'perf test'
regression testings

- Introduce the 'perf check', initially to check if some feature is
in place, using it in 'perf test'

- Various fixes for 32-bit systems

- Address more leak sanitizer failures

- Fix memory leaks (LBR, disasm lock ops, etc)

- More reference counting fixes (branch_info, etc)

- Constify 'struct perf_tool' parameters to improve code generation
and reduce the chances of having its internals changed, which isn't
expected

- More constifications in various other places

- Add more build tests, including for JEVENTS

- Add more 'perf test' entries ('perf record LBR', pipe/inject,
--setup-filter, 'perf ftrace', 'cgroup sampling', etc)

- Inject build ids for all entries in a call chain in 'perf inject',
not just for the main sample

- Improve the BPF based sample filter, allowing root to setup filters
in bpffs that then can be used by non-root users

- Allow filtering by cgroups with the BPF based sample filter

- Allow a more compact way for 'perf mem report' using the
-T/--type-profile and also provide a --sort option similar to the one
in 'perf report', 'perf top', to setup the sort order manually

where it was not showing anything even when other events in the group
had samples

- Fix spinlock and rwlock accounting in 'perf lock contention'

- Fix libsubcmd fixdep Makefile dependencies

- Improve 'perf ftrace' error message when ftrace isn't available

perf tests pmu: Initialize all fields of test_pmu variable

Instead of explicitely initializing just the .name and .alias_name,
use struct member named initialization of just the non-null -name field,
the compiler will initialize all the other non-explicitely initialized
fields to NULL.

This makes the code more robust, avoiding the error recently fixed when
the .alias_name was used and contained a random value.

perf test pmu: Set uninitialized PMU alias to null

Commit 3e0bf9fde2984469 ("perf pmu: Restore full PMU name wildcard
support") adds a test case "PMU cmdline match" that covers PMU name
wildcard support provided by function perf_pmu__match().

The test works with a wide range of supported combinations of PMU name
matching but omits the case that if the perf_pmu__match() cannot match
the PMU name to the wildcard, it tries to match its alias. However, this
variable is not set up, causing the test case to fail when run with
subprocesses or to segfault if run as a single process.

./perf test -vv 9
9: Sysfs PMU tests :
9.1: Parsing with PMU format directory : Ok
9.2: Parsing with PMU event : Ok
9.3: PMU event names : Ok
9.4: PMU name combining : Ok

Segmentation fault (core dumped)

Initialize the PMU alias to null for all tests of perf_pmu__match()
as this functionality is not being tested and the alias matching works
exactly the same as the matching of the PMU name.

Merge tag 'i2c-host-fixes-6.11-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current

The Aspeed driver tracks the controller's state (stop, pending,
start, etc.). Previously, when the stop command was sent, the
state was not updated. The fix in this pull request ensures the
driver's state is aligned with the device status.

The Intel SCH driver receives a new look, and among the cleanups,
there is a fix where, due to an oversight, an if/else statement
was missing the else, causing it to move forward instead of
exiting the function in case of an error.

The Qualcomm GENI I2C driver adds the IRQF_NO_AUTOEN flag to the
IRQ setup to prevent unwanted interrupts during probe.

The Xilinx XPS controller fixes TX FIFO handling to avoid missed
NAKs. Another fix ensures the controller is reinitialized when
the bus appears busy.
