[GIT pull] irq updates for 4.13

[Thomas Gleixner <tglx@linutronix.de>]

Linus,

please pull the latest irq-core-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-core-for-linus

The irq department delivers:

    - Expand the generic infrastructure handling the irq migration on CPU
      hotplug and convert X86 over to it. (Thomas Gleixner)

      Aside of consolidating code this is a preparatory change for:

    - Finalizing the affinity management for multi-queue devices. The main
      change here is to shut down interrupts which are affine to a outgoing
      CPU and reenabling them when the CPU comes online again. That avoids
      moving interrupts pointlessly around and breaking and reestablishing
      affinities for no value. (Christoph Hellwig)

      Note: This contains also the BLOCK-MQ and NVME changes which depend
      on the rework of the irq core infrastructure. Jens acked them and
      agreed that they should go with the irq changes.

    - Consolidation of irq domain code (Marc Zyngier)

    - State tracking consolidation in the core code (Jeffy Chen)

    - Add debug infrastructure for hierarchical irq domains (Thomas Gleixner)  

    - Infrastructure enhancement for managing generic interrupt chips via
      devmem (Bartosz Golaszewski)

    - Constification work all over the place (Tobias Klauser)

    - Two new interrupt controller drivers for MVEBU (Thomas Petazzoni)

    - The usual set of fixes, updates and enhancements all over the place.

Thanks,

	tglx
