Merge tag 'irq-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull interrupt subsystem updates from Thomas Gleixner:
"Core code:

- Interrupt storm detection for the lockup watchdog:

Lockups which are caused by interrupt storms are not easy to debug
because there is no information about the events which make the
lockup detector trigger.

To make this more user friendly, provide an extenstion to interrupt
statistics which allows to take snapshots and an interface to
retrieve the delta to the snapshot. Use this new mechanism in the
watchdog code to do a two stage lockup analysis by taking the
snapshot and printing the deltas for the topmost active interrupts
on the second trigger.

Note: This contains both the interrupt and the watchdog changes as
the latter depend on the former obviously.

- Avoid summation loops in the /proc/interrupts output and use the
global counter when possible

- Skip suspended interrupts on CPU hotplug operations to ensure that
they are not delivered before the system resumes the device drivers
when coming out of suspend.

- On CPU hot-unplug interrupts which are affine to the outgoing CPU
are migrated to a different CPU in the affinity mask. This can fail
when the CPUs have no vectors left. Instead of giving up try to
migrate it to any online CPU and thereby breaking the affinity
setting in order to prevent a stale device interrupt which targets
an offline CPU

- The usual small cleanups

Driver code:

- Support for the RISCV AIA MSI controller

- Make the interrupt allocation for the Loongson PCH controller more
flexible to prevent vector exhaustion

- The usual set of cleanups and fixes all over the place"

genirq: Provide a snapshot mechanism for interrupt statistics

The soft lockup detector lacks a mechanism to identify interrupt storms as
root cause of a lockup. To enable this the detector needs a mechanism to
snapshot the interrupt count statistics on a CPU when the detector observes
a potential lockup scenario and compare that against the interrupt count
when it warns about the lockup later on. The number of interrupts in that
period give a hint whether the lockup might have been caused by an interrupt
storm.

Instead of having extra storage in the lockup detector and accessing the
internals of the interrupt descriptor directly, add a snapshot member to
the per CPU irq_desc::kstat_irq structure and provide interfaces to take a
snapshot of all interrupts on the current CPU and to retrieve the delta of
a specific interrupt later on.

Pull irq updates from Thomas Gleixner:
"Updates for the interrupt subsystem:

Core:

- Move the interrupt affinity spreading mechanism into lib/group_cpus
so it can be used for similar spreading requirements, e.g. in the
block multi-queue code

This also contains a first usecase in the block multi-queue code
which Jens asked to take along with the librarization

- Improve irqdomain locking to close a number race conditions which
can be observed with massive parallel device driver probing

- Enforce and document the semantics of disable_irq() which cannot be
invoked safely from non-sleepable context

- Move the IPI multiplexing code from the Apple AIC driver into the
core, so it can be reused by RISCV

Drivers:

- Plug OF node refcounting leaks in various drivers

- Correctly mark level triggered interrupts in the Broadcom L2
drivers

- The usual small fixes and improvements

- No new drivers for the record!"
