Merge tag 'irq-core-2025-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

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"

softirq: Allow to drop the softirq-BKL lock on PREEMPT_RT

individual sections which disable bottom halves. This in turn means

softirq: Allow to drop the softirq-BKL lock on PREEMPT_RT

softirqs are preemptible on PREEMPT_RT. There is synchronisation between
individual sections which disable bottom halves. This in turn means that
a forced threaded interrupt cannot preempt another forced threaded
interrupt. Instead it will PI-boost the other handler and wait for its
completion.

This is required because code within a softirq section is assumed to be
non-preemptible and may expect exclusive access to per-CPU resources
such as variables or pinned timers.

Code with such expectation has been identified and updated to use
local_lock_nested_bh() for locking of the per-CPU resource. This means the
softirq lock can be removed.

Disable the softirq synchronization, but add a new config switch
CONFIG_PREEMPT_RT_NEEDS_BH_LOCK which allows to re-enable the synchronized
behavior in case that there are issues, which haven't been detected yet.

The softirq_ctrl.cnt accounting remains to let the NOHZ code know if
softirqs are currently handled.
