Public bug reported:
Since 6.16, TDX host is supported in the kernel but is incompatible with kexec.
A cache flush is required in case TDX has been enabled before doing a kexec to
avoid silent memory corruption in the new kernel.
An upstream submission fix this, the limitation is the second kernel cannot use
TDX itself.
The submission is now a v8 and is likely to be merged soon.
This has been applied on top of questing Ubuntu-6.17.0-3.3 and tested on
supported hardware by enabling TDX and then kexec into a new kernel.
