Bug Description

[Impact]

CONFIG_INTEL_TDX_HOST depends on !KEXEC_CORE in the latest 6.8 kernel. This was introduced by:

 cb8eb06d50fc ("x86/virt/tdx: Disable TDX host support when kexec is enabled")

We cannot regress kexec, therefore we need to disable CONFIG_INTEL_TDX_HOST in the generic kernel, despite our attempt with LP: #2046040.

[Fix]

Disable CONFIG_INTEL_TDX_HOST in the generic kernel, until upstream will properly support this option with kexec.

[Regression potential]

The Intel host TDX feature won't be available in the generic kernel.
