Pull irq chip driver updates from Thomas Gleixner:
- Use the startup/shutdown callbacks for the PCI/MSI per device
interrupt domains.
This allows us to initialize the RISCV PLIC interrupt hierarchy
correctly and provides a mechanism to decouple the masking and
unmasking during run-time from the expensive PCI mask and unmask when
the underlying MSI provider implementation allows the interrupt to be
masked.
- Initialize the RISCV PLIC MSI interrupt hierarchy correctly so that
the affinity assignment works correctly by switching it over to the
startup/shutdown scheme
- Allow MSI providers to opt out from masking a PCI/MSI interrupt at
the PCI device during operation when the provider can mask the
interrupt at the underlying interrupt chip. This reduces the overhead
in scenarios where disable_irq()/enable_irq() is utilized frequently
by a driver.
The PCI/MSI device level [un]masking is only required on startup and
shutdown in this case.
- Remove the conditional mask/unmask logic in the PCI/MSI layer as this
is now handled unconditionally.
- Replace the hardcoded interrupt routing in the Loongson EIOINTC
interrupt driver to respect the firmware settings and spread them out
to different CPU interrupt inputs so that the demultiplexing handler
only needs to read only a single 64-bit status register instead of
four, which significantly reduces the overhead in VMs as the status
register access causes a VM exit.
- Add support for the new AST2700 SCU interrupt controllers
- Use the legacy interrupt domain setup for the Loongson PCH-LPC
interrupt controller, which resembles the x86 legacy PIC setup and
has the same hardcoded legacy requirements.
- The usual set of cleanups, fixes and improvements all over the place

Pull irq core updates from Thomas Gleixner:
"A set of updates for the interrupt core subsystem:
- Introduce irq_chip_[startup|shutdown]_parent() to prepare for
addressing a few short comings in the PCI/MSI interrupt subsystem.
It allows to utilize the interrupt chip startup/shutdown callbacks
for initializing the interrupt chip hierarchy properly on certain
RISCV implementations and provides a mechanism to reduce the
overhead of masking and unmasking PCI/MSI interrupts during
operation when the underlying MSI provider can mask the interrupt.
The actual usage comes with the interrupt driver pull request.
- Add generic error handling for devm_request_*_irq()
This allows to remove the zoo of random error printk's all over the
usage sites.
- Add a mechanism to warn about long-running interrupt handlers
Long running interrupt handlers can introduce latencies and
tracking them down is a tedious task. The tracking has to be
enabled with a threshold on the kernel command line and utilizes a
static branch to remove the overhead when disabled.
- Update and extend the selftests which validate the CPU hotplug
interrupt migration logic
- Allow dropping the per CPU softirq lock on PREEMPT_RT kernels,
which causes contention and latencies all over the place.
The serialization requirements have been pushed down into the
actual affected usage sites already.
- The usual small cleanups and improvements"

Introduce a new document, flow_control.rst, to provide a comprehensive
guide on Ethernet Flow Control in Linux. The guide explains how flow
control works, how autonegotiation resolves pause capabilities, and how
to configure it using ethtool and Netlink.
In parallel, document the pause and pause-stat attributes in the
ethtool.yaml netlink spec. This enables the ynl tool to generate
kernel-doc comments for the corresponding enums in the UAPI header,
making the C interface self-documenting.
Finally, replace the legacy flow control section in phy.rst with a
reference to the new document and add pointers in the relevant C source
files.

Pull arm64 updates from Will Deacon:
"There's good stuff across the board, including some nice mm
improvements for CPUs with the 'noabort' BBML2 feature and a clever
patch to allow ptdump to play nicely with block mappings in the
vmalloc area.
Confidential computing:
- Add support for accepting secrets from firmware (e.g. ACPI CCEL)
and mapping them with appropriate attributes.
CPU features:
- Advertise atomic floating-point instructions to userspace
- Extend Spectre workarounds to cover additional Arm CPU variants
- Extend list of CPUs that support break-before-make level 2 and
guarantee not to generate TLB conflict aborts for changes of
mapping granularity (BBML2_NOABORT)
- Add GCS support to our uprobes implementation.
Documentation:
- Remove bogus SME documentation concerning register state when
entering/exiting streaming mode.
Entry code:
- Switch over to the generic IRQ entry code (GENERIC_IRQ_ENTRY)
- Micro-optimise syscall entry path with a compiler branch hint.
Memory management:
- Enable huge mappings in vmalloc space even when kernel page-table
dumping is enabled
- Tidy up the types used in our early MMU setup code
- Rework rodata= for closer parity with the behaviour on x86
- For CPUs implementing BBML2_NOABORT, utilise block mappings in the
linear map even when rodata= applies to virtual aliases
- Don't re-allocate the virtual region between '_text' and '_stext',
as doing so confused tools parsing /proc/vmcore.
Miscellaneous:
- Clean-up Kconfig menuconfig text for architecture features
- Avoid redundant bitmap_empty() during determination of supported
SME vector lengths
- Re-enable warnings when building the 32-bit vDSO object
- Avoid breaking our eggs at the wrong end.
Perf and PMUs:
- Support for v3 of the Hisilicon L3C PMU
- Support for Hisilicon's MN and NoC PMUs
- Support for Fujitsu's Uncore PMU

Pull vfs mount updates from Christian Brauner:
"This contains some work around mount api handling:
- Output the warning message for mnt_too_revealing() triggered during
fsmount() to the fscontext log. This makes it possible for the
mount tool to output appropriate warnings on the command line.
For example, with the newest fsopen()-based mount(8) from
util-linux, the error messages now look like:
# mount -t proc proc /tmp
mount: /tmp: fsmount() failed: VFS: Mount too revealing.
dmesg(1) may have more information after failed mount system call.
- Do not consume fscontext log entries when returning -EMSGSIZE
Userspace generally expects APIs that return -EMSGSIZE to allow for
them to adjust their buffer size and retry the operation.
However, the fscontext log would previously clear the message even
in the -EMSGSIZE case.
Given that it is very cheap for us to check whether the buffer is
too small before we remove the message from the ring buffer, let's
just do that instead.
- Drop an unused argument from do_remount()"

Pull misc vfs updates from Christian Brauner:
"This contains the usual selections of misc updates for this cycle.
Features:
- Add "initramfs_options" parameter to set initramfs mount options.
This allows to add specific mount options to the rootfs to e.g.,
limit the memory size
- Add RWF_NOSIGNAL flag for pwritev2()
Add RWF_NOSIGNAL flag for pwritev2. This flag prevents the SIGPIPE
signal from being raised when writing on disconnected pipes or
sockets. The flag is handled directly by the pipe filesystem and
converted to the existing MSG_NOSIGNAL flag for sockets
- Allow to pass pid namespace as procfs mount option
Ever since the introduction of pid namespaces, procfs has had very
implicit behaviour surrounding them (the pidns used by a procfs
mount is auto-selected based on the mounting process's active
pidns, and the pidns itself is basically hidden once the mount has
been constructed)
This implicit behaviour has historically meant that userspace was
required to do some special dances in order to configure the pidns
of a procfs mount as desired. Examples include:
* In order to bypass the mnt_too_revealing() check, Kubernetes
creates a procfs mount from an empty pidns so that user
namespaced containers can be nested (without this, the nested
containers would fail to mount procfs)
But this requires forking off a helper process because you cannot
just one-shot this using mount(2)
* Container runtimes in general need to fork into a container
before configuring its mounts, which can lead to security issues
in the case of shared-pidns containers (a privileged process in
the pidns can interact with your container runtime process)
While SUID_DUMP_DISABLE and user namespaces make this less of an
issue, the strict need for this due to a minor uAPI wart is kind
of unfortunate
Things would be much easier if there was a way for userspace to
just specify the pidns they want. So this pull request contains
changes to implement a new "pidns" argument which can be set
using fsconfig(2):
fsconfig(procfd, FSCONFIG_SET_FD, "pidns", NULL, nsfd);
fsconfig(procfd, FSCONFIG_SET_STRING, "pidns", "/proc/self/ns/pid", 0);
or classic mount(2) / mount(8):
// mount -t proc -o pidns=/proc/self/ns/pid proc /tmp/proc
mount("proc", "/tmp/proc", "proc", MS_..., "pidns=/proc/self/ns/pid");
Cleanups:
- Remove the last references to EXPORT_OP_ASYNC_LOCK
- Make file_remove_privs_flags() static
- Remove redundant __GFP_NOWARN when GFP_NOWAIT is used
- Use try_cmpxchg() in start_dir_add()
- Use try_cmpxchg() in sb_init_done_wq()
- Replace offsetof() with struct_size() in ioctl_file_dedupe_range()
- Remove vfs_ioctl() export
- Replace rwlock() with spinlock in epoll code as rwlock causes

through automounts, but could still trigger them

Kohli)
- Support fallback trimming values when the fuse is empty in the R-Car
driver (Marek Vasut)
- Remove unneeded semicolon in the Mediatek LVTS driver (Jiapeng
Chong)
- Fix the LMH Kconfig option by selecting QCOM_SCM and take the
opportunity to add the COMPILE_TEST option for the QCom's LMH
feature (Dmitry Baryshkov)
- Fix the missing includes and incorrect error message in the Qcom's
LMH driver (Dmitry Baryshkov)
- Fix comment typo and add the documentation in the Kconfig for the
R-Car Gen3 and Gen4 (Marek Vasut)
- Add Tegra114 SOCTHERM support (Svyatoslav Ryhel)
- Rename the functions name in the driver to be consistent and generic
with the different R-Car platform variants (Wolfram Sang)
- Register the TI K3 J72xx bandgap sensor as a hwmon sensor too
(Michael Walle)
- Add and document the thermal sensor unit reporting the junction
temperature of the RZ/G3S SoC (Claudiu Beznea)
