Subject: [PATCH v2 11/15] nds32: define syscall_get_arch()
Message-ID: <20181120001620.GK11387@altlinux.org>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
In-Reply-To: <20181120001128.GA11300@altlinux.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

syscall_get_arch() is required to be implemented on all architectures
in order to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO
request.
