This commit makes checklitmus.sh and checkalllitmus.sh check to see if a hardware verification was specified (via the --hw command-line argument, which sets the LKMM_HW_MAP_FILE environment variable). If so, the C-language litmus test is converted to the specified type of assembly-language litmus test and herd is run on it. Hardware is permitted to be stronger than LKMM requires, so "Always" and "Never" verifications of "Sometimes" C-language litmus tests are forgiven. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
