# Work-around for distro-specific public modules ABI breakages.
# Some distributions break the public module instrumentation ABI
# compared to upstream stable kernels without providing other mean than
# the kernel EXTRAVERSION to figure it out. Translate this information
# into a define visible from the C preprocessor.
