These calls are buildable on common sanitycheck platforms, but are not invoked at runtime in any tests accessible to CI. The changes are mostly mechanical, so the risk is low, but this commit is separated from the main API change to allow for more careful review. Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
