Mao Han b4bf274198 csky: Add perf_arch_fetch_caller_regs support ... In trace events as tracepoints context are not able to be retrieve with task_pt_regs. Without arch caller regs support the pt_regs context will be all zero, perf can not parsing the callchain and resolving the symbols correctly, some time will even get into deadlock while handling the page fault, eg: perf kmem —page record ls Changelog - Add test case cmd in comment - Use regs_fp(regs) which is defined in abi/regdef.h Signed-off-by: Mao Han <han_mao@c-sky.com> Signed-off-by: Guo Ren <guoren@kernel.org>		2019-04-22 13:44:57 +08:00
