2015-10-22	genirq: Make the cpuhotplug migration code less noisy	Thomas Gleixner	1	-1/+1
	The original arm code has a pr_debug() statement for the case where the irq chip has no set_affinity() callback. That's sufficient for debugging and we really don't want to spam dmesg with useless warnings for the normal case.

2015-10-01	genirq: Introduce generic irq migration for cpu hotunplug	Yang Yingliang	1	-0/+82
	ARM and ARM64 have almost identical code for migrating interrupts on cpu hotunplug. Provide a generic version which can be used by both. The new code addresses a shortcoming in the ARM[64] variants which fails to update the affinity change in some cases. The solution for this is to use the core function irq_do_set_affinity() instead of open coding it. [ tglx: Added copyright notice and license boilerplate.
