I still believe calling cc_platform_has() from __startup_64() is totally
broken as it lacks proper wrapping while accessing global variables.
Well, one of the issues on the AMD side was using boot_cpu_data too
early and the Intel side uses it too. Can you replace those checks with
is_tdx_guest() or whatever was the helper's name which would check
whether the the kernel is running as a TDX guest, and see if that helps?
There's no need in Intel check this early. Only AMD need it. Maybe just
opencode them?
Any way you can put a gzipped/bzipped copy of your vmlinux file somewhere
I can grab it from and take a look at it?
Thanks,
Tom
