From 67f2a8a29311841ba6ab9b0e2d1b8f1e9978cd84 Mon Sep 17 00:00:00 2001 From: "Dmitry V. Levin" Date: Mon, 18 Mar 2019 02:28:47 +0300 Subject: [PATCH] arc: define syscall_get_arch() syscall_get_arch() is required to be implemented on all architectures in addition to already implemented syscall_get_nr(), syscall_get_arguments(), syscall_get_error(), and syscall_get_return_value() functions in order to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.
