If memory is this scarce, why not set CONFIG_TRANSPARENT_HUGEPAGE=n and be done
with it? If the config option is enabled, the admin should be able to turn the
functionality back on if desired. If you really don't _ever_ want THP then
disable the config.

Unfortunately, changing .config is not always as easy as you said,
for the kdump case, we use the same kernel binary with the normal kernel
which certainly has to have THP enabled in .config.
