arm: mvebu: Use local interrupt only for the timer 0
The commit 3a6f08a3 "arm: mvebu: Add support for local interrupt", managed the 28th first interrupts as local interrupt to match the hardware specification. Among these interrupts there are the Gigabits Ethernet ones used by the mvneta driver. Unfortunately the state of the percpu_irq API prevents the driver to use it. Indeed the interrupts have to be freed when the .stop() function is called. As the free_percpu_irq() function don't disable the interrupt line, we have to do it on each CPU before calling this. The function disable_percpu_irq() only disable the percpu on the current CPU and there is no function which allows to disable a percpu irq on a given CPU. Waiting for the extension of the percpu_irq API, this fix allows to use again the mvneta driver. Signed-off-by:Gregory CLEMENT <gregory.clement@free-electrons.com> Tested-by:
