Hi, is it supposed to work on x86_64? It doesn't compile. I tried to fix the compilation errors with these 2 one-liners:

It now compiles. When I try to run it, I get instant reboot after "BIOS data check successful".
This is not necessarily a new issue. I haven't tried running realtime-preempt on x86_64 before.
