From 92f922f35078245e2acbafcf74fb1947dbbac398 Mon Sep 17 00:00:00 2001 From: "Dmitry V. Levin" Date: Mon, 18 Mar 2019 02:29:38 +0300 Subject: m68k: 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.

The primary intent is that the triple (audit_arch, syscall_nr, arg1..arg6) should describe what system call is being called and what its arguments are.
