I could split the patch but it is not testable/usable without the CPU count fix/hack.

But I am now preparing the IFUNC patch for glibc upstreaming, whether it will be accepted or not.

As long as you do not want a temporary solution in CRaC we can suspend this patch until glibc upstreaming gets resolved.
