Public bug reported:
[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.
