Handle cases where the RMP table placement in the BIOS is
not 2M aligned and then the kexec kernel could try to allocate
from within that chunk and that causes a fatal RMP fault.
Is this something that happens on existing systems currently so that it
needs to be fixed upstream?

Patch 2/2 - includes the following Fixes tag, do i need to include the Fixes tag in the cover letter too ?

Fixes: c3b86e61b756 ("x86/cpufeatures: Enable/unmask SEV-SNP CPU feature")

Thanks,
Ashish
