c6x: define syscall_get_arch() (a43e6647) · Commits · 戴 / test

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.
