Revision 9dae41a238a952eb65c8aa8a59d8aa39058a7bcf authored by Linus Torvalds on 20 August 2017, 16:07:56 UTC, committed by Linus Torvalds on 20 August 2017, 16:07:56 UTC 
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"
