Merge branch 'queue/irq/arm' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next/cleanup
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
