Subject: [PATCH v6 0/2] x86/sev: Fixes for SEV-ES Guest Support

From: Joerg Roedel <jroedel@...e.de>

Hi,

here are the remainig patches in my queue for SEV-ES guest support.
Changes to the previous version are:

	- Rebased to tip/x86/sev
	- Merged Boris' diff to patch 1 and fixed two minor issues in
	  the result

The patches are again tested with a kernel with various debuggin
options enabled, running as an SEV-ES guest.

The previous version of these patches can be found here:

	https://lore.kernel.org/lkml/20210614135327.9921-1-joro@8bytes.org/

Please review.

Thanks,

	Joerg
