The SEV-ES bit of Fn800-001F[EAX] - Bit 3 is used for a host to

the SEV_STATUS MSR Bit 1 to determine if SEV-ES is enabled.
Worth mentioning in the commit message that this check wasn't part of the
original SEV-ES support (Fixes: a91b700e385e7484ab7286b3ba7ea2efbd59480e
tag?), so this is really a compatibility thing, and that this makes the
check consistent with the Linux kernel.
Sure I update the commit message in the V2 with this info and add the
Fixes tag. Do I need a (Fixes:
b461d67639f2deced77e9bb967d014b7cfcd75f8) tag too? Since the Check was
moved between files in that commit?
I don't think so, but that's just my opinion.
Thanks,
Tom
