Hello, This is for interrupt chained handlers to properly handle the primary controller using chained_irq_enter and chained_irq_exit functions. Without this, chained interrupts connected to GIC would not work properly. This patch series contains: [PATCH 1/3] ARM: SAMSUNG: add entry and exit functions for uart interrupt chained handler [PATCH 2/3] ARM: SAMSUNG: add entry and exit functions for pwm interrupt chained handler [PATCH 3/3] ARM: EXYNOS4: add entry and exit functions for external interrupt chained handler Best regards, Changhwan Youn Patch summary: Changhwan Youn (3): ARM: SAMSUGN: add entry and exit functions for uart interrupt chained handler ARM: SAMSUNG: add entry and exit functions for pwm interrupt chained handler ARM: EXYNOS4: add entry and exit functions for external interrupt chained handler arch/arm/mach-exynos4/irq-eint.c | 14 +++++++------- arch/arm/plat-samsung/irq-uart.c | 6 ++++++ arch/arm/plat-samsung/irq-vic-timer.c | 5 +++++ 3 files changed, 18 insertions(+), 7 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
