Merge "ARM: Interrupt cleanups and API change preparation" from Thomas
Gleixner:

The following patch series contains the following changes:

    - Consolidation of chained interrupt handler setup/removal

    - Switch to functions which avoid a redundant interrupt
      descriptor lookup

    - Preparation of interrupt flow handlers for the 'irq' argument
      removal

* 'queue/irq/arm' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  ARM/orion/gpio: Prepare gpio_irq_handler for irq argument removal
  ARM/pxa: Prepare balloon3_irq_handler for irq argument removal
  ARM/pxa: Prepare *_irq_handler for irq argument removal
  ARM/dove: Prepare pmu_irq_handler for irq argument removal
  ARM/sa1111: Prepare sa1111_irq_handler for irq argument removal
  ARM/locomo: Prepare locomo_handler for irq argument removal
  ARM, irq: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc
  ARM/LPC32xx: Use irq_set_handler_locked()
  ARM/irq: Use access helper irq_data_get_affinity_mask()
  ARM/locomo: Consolidate chained IRQ handler install/remove
  ARM/orion: Consolidate chained IRQ handler install/remove
