Hi,
Please cherry-pick following 6 patches to 6.14:
bc3e5f48b7ee021371dc37297678f7089be6ce28 accel/ivpu: Use workqueue for IRQ handling
0240fa18d247c99a1967f2fed025296a89a1c5f5 accel/ivpu: Dump only first MMU fault from single context
4480912f3f8b8a1fbb5ae12c5c547fd094ec4197 accel/ivpu: Move parts of MMU event IRQ handling to thread handler
353b8f48390d36b39276ff6af61464ec64cd4d5c accel/ivpu: Fix missing MMU events from reserved SSID
2f5bbea1807a064a1e4c1b385c8cea4f37bb4b17 accel/ivpu: Fix missing MMU events if file_priv is unbound
683e9fa1c885a0cffbc10b459a7eee9df92af1c1 accel/ivpu: Flush pending jobs of device's workqueues
These are fixing an issue where host can be overloaded with MMU faults from NPU causing other IRQs to be missed and host to be slowed down significantly.
They should apply without conflicts.
Thanks,
Jacek
