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 pile of smallish changes all over the place:
- Add a missing ISB in the GIC V1 driver
- Remove an ACPI version check in the GIC V3 ITS driver
- Add the missing irq_pm_shutdown function for BRCMSTB-L2 to avoid
spurious wakeups
- Remove the artifical limitation of ITS instances to the number of
NUMA nodes which prevents utilizing the ITS hardware correctly
- Prevent a infinite parsing loop in the GIC-V3 ITS/MSI code
- Honour the force affinity argument in the GIC-V3 driver which is
required to make perf work correctly
- Correctly report allocation failures in GIC-V2/V3 to avoid using
half allocated and initialized interrupts.
- Fixup checks against nr_cpu_ids in the generic IPI code"
