Later patches in the series then carry out more or less unrelated changes (hopefully improvements) noticed while looking at various pieces of involved code. 01: deal with move-in-progress state in fixup_irqs() 02: deal with move cleanup count state in fixup_irqs() 03: avoid UB (or worse) in trace_irq_mask() 04: improve dump_irqs() 05: desc->affinity should strictly represent the requested value 06: consolidate use of ->arch.cpu_mask 07: fix locking around vector management 08: correct/tighten vector check in _clear_irq_vector() 09: make fixup_irqs() skip unconnected internally used interrupts 10: reduce unused space in struct arch_irq_desc 11: drop redundant cpumask_empty() from move_masked_irq() 12: simplify and rename pirq_acktype() In principle patches 1-3, 5-7, and maybe 9 are backporting candidates. Their intrusive nature makes wanting to do so questionable, though. I'm omitting the final v1 "x86/IO-APIC: drop an unused variable from setup_IO_APIC_irqs()" here, as it was acked already and is entirely independent of this series. For other v2 specific information please see the individual patches. Jan
