2020-05-13	csky: Fixup calltrace panic	Guo Ren
	The implementation of show_stack will panic with wrong fp: addr = *fp++; because the fp isn't checked properly. The current implementations of show_stack, wchan and stack_trace haven't been designed properly, so just deprecate them. This patch is a reference to riscv's way, all codes are modified from arm's. The patch is passed with: - cat /proc/<pid>/stack - cat /proc/<pid>/wchan - echo c > /proc/sysrq-trigger Signed-off-by: Guo Ren <guoren@linux.alibaba.com>
2018-12-31	csky: stacktrace supported.	Guo Ren
	The gcc option "-mbacktrace" will push fp(r8),lr into stack and we could unwind the stack with: fp = fp lr = (unsigned int )fp[1] Signed-off-by: Guo Ren <ren_guo@c-sky.com>
