Pull x86 fix from Borislav Petkov:
- 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
