Guo Ren 18c07d23da csky: Fixup calltrace panic ... 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>		2020-05-13 17:55:06 +08:00
