Guo Ren	0f231dcfc6	csky: coding convention: Use task_stack_page ... Use task_stack_page instead of p->stack to get stack. Follow the coding convention style. Also for init_stack, the same with other archs. Signed-off-by: Guo Ren <ren_guo@c-sky.com>	2019-02-13 09:48:14 +08:00
Guo Ren	859e5f45cb	csky: CPU-hotplug supported for SMP ... This is a simple implement of CPU-hotplug for power saving. CPU use wait instruction to enter power saving mode and waiting for IPI wakeup signal. Signed-off-by: Guo Ren <ren_guo@c-sky.com>	2018-12-31 23:03:53 +08:00
Yangtao Li	398539dd69	csky: Don't leak device tree node reference ... of_find_node_by_type() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. setup_smp() doesn't do that, so fix it by converting to for_each_of_cpu_node().
