Subject: [PATCH v2 05/15] powerpc/uaccess: Move get_user_instr helpers in
 asm/inst.h
To:     Benjamin Herrenschmidt <benh@kernel.crashing.org>,
        Paul Mackerras <paulus@samba.org>,
        Michael Ellerman <mpe@ellerman.id.au>
Cc:     linux-kernel@vger.kernel.org, linuxppc-dev@lists.ozlabs.org
Date:   Wed, 10 Mar 2021 17:46:44 +0000 (UTC)
Precedence: bulk

Those helpers use get_user helpers but they don't participate
in their implementation, so they do not belong to asm/uaccess.h

Move them in asm/inst.h
