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.
