Wayne Ren 601b9afc9e arch: arc: implement DIRECT IRQ support ... * implement DIRECT IRQ support both for normal irq and fast irq. * add separate interrupt stack for fast irq and use CONFIG_ARC_ _FIRQ_STACK to control it. This will bring shortest interrupt latency for fast irq. * note that scheduing in DIRECT IRQ is not supported. Signed-off-by: Wayne Ren <wei.ren@synopsys.com>		2019-10-21 09:06:17 -07:00
