Hi,
here are a couple of fixes for 5.12 in the SEV-ES guest support code.
Patches 1-3 have in a similar form already been posted, so this is v2.
The last two patches are new an arose from me running an SEV-ES guest
with more debugging features and instrumentation enabled. I changed
the first patches according to the review comments I received.
Please review.
Thanks,
Joerg
