Pull irq updates from Thomas Gleixner:
 "Updates for the interrupt subsystem:

  Core:
   - Allow trimming of interrupt hierarchy to support odd hardware
     setups where only a subset of the interrupts requires the full
     hierarchy.

   - Allow the retrigger mechanism to follow a hierarchy to simplify
     driver code.

   - Provide a mechanism to force enable wakeup interrrupts on suspend.

   - More infrastructure to handle IPIs in the core code

  Architectures:
   - Convert ARM/ARM64 IPI handling to utilize the interrupt core code.

  Drivers:
   - The usual pile of new interrupt chips (MStar, Actions Owl, TI
     PRUSS, Designware ICTL)

   - ARM(64) IPI related conversions

   - Wakeup support for Qualcom PDC

   - Prevent hierarchy corruption in the NVIDIA Tegra driver

   - The usual small fixes, improvements and cleanups all over the
     place"
