Linus Torvalds 4c605260bc - Set up the kernel CS earlier in the boot process in case EFI boots the 
kernel after bypassing the decompressor and the CS descriptor used
   ends up being the EFI one which is not mapped in the identity page
   table, leading to early SEV/SNP guest communication exceptions
   resulting in the guest crashing

   the kernel after bypassing the decompressor and the CS descriptor
   used ends up being the EFI one which is not mapped in the identity
