The Linux signature uses long, also this allows for making _sys_call and friends architecture-independent. * lib/linux/x86-mes-mescc/syscall-internal.c (__sys_call_internal, __sys_call2_internal): Use long. Update callers. * lib/linux/x86-mes-mescc/syscall.c (__sys_call, __sys_call1, __sys_call2, __sys_call3, __sys_call4, _sys_call, _sys_call1, _sys_call2, _sys_call3, _sys_call4): Likewise.
