You could find inspiration in
tools/testing/selftests/livepatch/test-livepatch.sh, see

load_lp $MOD_REPLACE replace=0

vs.

load_lp $MOD_REPLACE replace=1

You could more or less copy the "multiple livepatches" and
"atomic replace livepatch" self-tests. The new tests
would check the "stack_order" sysfs value instread of checking
whether /proc/cmdline and /proc/meminfo are livepatched.
