[PATCH 0/5 v2] x86/sev-es: SEV-ES Fixes for v5.12

[Joerg Roedel]

From: Joerg Roedel <jroedel@xxxxxxx>

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
