Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner:
- A few fixes mopping up the fallout of the big irq overhaul
- Move the interrupt resource management logic out of the spin locked,
irq disabled region to avoid unnecessary restrictions of the resource
callbacks
- Preparation for reworking the per cpu irq request function.
* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
irqdomain: Allow ACPI device nodes to be used as irqdomain identifiers
genirq/debugfs: Remove redundant NULL pointer check
genirq: Allow to pass the IRQF_TIMER flag with percpu irq request
genirq/timings: Move free timings out of spinlocked region
genirq: Move irq resource handling out of spinlocked region
genirq: Add mutex to irq desc to serialize request/free_irq()
genirq: Move bus locking into __setup_irq()
genirq: Force inlining of __irq_startup_managed to prevent build failure
genirq/debugfs: Fix build for !CONFIG_IRQ_DOMAIN
