Subject: [PATCH] powerpc: define the variable 'uaccess_flush' as static
Date:   Fri, 12 Mar 2021 06:06:38 -0500
Message-ID: <20210312110638.178974-1-heying24@huawei.com>

Precedence: bulk

The variable 'uaccess_fulsh' is not referenced outside the file. Perhaps we
should define it as static to avoid the warning as follows:

arch/powerpc/kernel/setup_64.c:953:6: warning: symbol 'uaccess_flush'
was not declared. Should it be static?
