Subject: [PATCH V4 0/3] riscv: Add perf callchain support
This patch set add perf callchain(FP/DWARF) support for RISC-V.
It comes from the csky version callchain support with some
slight modifications. The patchset base on Linux 5.3.
Changes since v3:
- Add more strict check for unwind_frame_kernel
- update for kernel 5.3
Changes since v2:
- fix inconsistent comment
- force to build kernel with -fno-omit-frame-pointer if perf
event is enabled
Changes since v1:
- simplify implementation and code convention
