Subject: [PATCH 3/5] sh: don't use asm-generic/ptrace.h
Date:   Mon, 24 Jun 2019 07:47:26 +0200

Precedence: bulk

Doing the indirection through macros for the regs accessors just
makes them harder to read, so implement the helpers directly.

Note that only the helpers actually used are implemented now.
