Revision e53f21bce4d35a93b23d8fa1a840860f6c74f59e authored by Catalin Marinas on 23 March 2015, 15:06:50 UTC, committed by Catalin Marinas on 23 March 2015, 18:42:23 UTC
The idle_task_exit() function may call switch_mm() with next == &init_mm. On arm64, init_mm.pgd cannot be used for user mappings, so this patch simply sets the reserved TTBR0.
