From: "Dmitry V. Levin" <ldv@xxxxxxxxxxxx>
Subject: parisc: define syscall_get_error()
syscall_get_error() is required to be implemented on all architectures in
addition to already implemented syscall_get_nr(), syscall_get_arguments(),
syscall_get_return_value(), and syscall_get_arch() functions in order to
extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.
