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 Signed-off-by: Olof Johansson <olof@lixom.net>
