Merge tag 'irq-core-2026-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

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

   - Remove the interrupt timing infrastructure

     This was added seven years ago to be used for power management
     purposes, but that integration never happened.

   - Clean up the remaining setup_percpu_irq() users

     The memory allocator is available when interrupts can be requested
     so there is not need for static irq_action. Move the remaining
     users to request_percpu_irq() and delete the historical cruft.

   - Warn when interrupt flag inconsistencies are detected in
     request*_irq().

     Inconsistent flags can lead to hard to diagnose malfunction. The
     fallout of this new warning has been addressed in next and the
     fixes are coming in via the maintainer trees and the tip
     irq/cleanup pull requests.

   - Invoke affinity notifier when CPU hotplug breaks affinity

     Otherwise the code using the notifier misses the affinity change
     and operates on stale information.

   - The usual cleanups and improvements"
