Subject: [PATCH V4 0/3] riscv: Add perf callchain support
Date:   Tue, 20 Aug 2019 16:57:15 +0800
Message-Id: <cover.1566290744.git.han_mao@c-sky.com>

Precedence: bulk

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
