Thanks. I am applying the patch to git master and v1.11 branches. I tested my static build of lstopo-no-graphics on Android 6 on aarch64 [1], it still works without disabling openat. It's not running as an APK, but it's running inside a shell that was launched by an APK (sshdroid, a ssh server shell). Not sure why this would be different?
