[PATCH V2 1/1] GIC: introduce method to deactive interupts

2014-08-03 Thread Liu Hua
When using kdump on ARM platform, if kernel panics in interrupt handler (maybe PPI), the capture kernel can not recive certain interrupt, and fails to boot. On this situation, We have read register GICC_IAR. But we have no chance to write relative bit to register GICC_EOIR (kernel paniced before)
