For example, "--hw AArch64" will specify that a C-language litmus test is to be translated to ARMv8 and the result verified. This will set the LKMM_HW_MAP_FILE environment variable accordingly. If there is no --hw argument, this environment variable will be set to the empty string. Signed-off-by: Paul E.
