The patchset adds bits and pieces to get kexec (and crashkernel) work on

The last patch implements CPU offlining according to the approved ACPI
spec change poposal[1]. It unlocks kexec with all CPUs visible in the target
kernel. It requires BIOS-side enabling. If it missing we fallback to booting
2nd kernel with single CPU.

Please review. I would be glad for any feedback.

Hi Kirill,

I have a very basic question: is there a reason why this series does not revert commit cb8eb06d50fc, "x86/virt/tdx: Disable TDX host support when kexec is enabled"?

Thanks,

Paolo
