Subject: [PATCH] arch: Cleanup unused functions
Date:   Tue, 25 May 2021 12:20:34 +0000
Message-Id: <1621945234-37878-1-git-send-email-guoren@kernel.org>
Precedence: bulk

From: Guo Ren <guoren@linux.alibaba.com>

These functions haven't been used, so just remove them. The patch
has been tested with riscv, but I only use grep to check the
microblaze's.
