Subject: [V4 0/8] KVM: selftests: Add simple SEV test

This patch series continues the work Michael Roth has done in supporting
SEV guests in selftests. It continues on top of the work Sean
Christopherson has sent to support ucalls from SEV guests. Along with a
very simple version of the SEV selftests Michael originally proposed.

V4
 * Rebase ontop of seanjc@'s latest Ucall Pool series:
   https://lore.kernel.org/linux-arm-kernel/20220825232522.3997340-8-seanjc@google.com/
 * Fix up review comments from seanjc
 * Switch authorship on 2 patches because of significant changes, added
 * Michael as suggested-by or originally-by.

V3
 * Addressed more of andrew.jones@ in ucall patches.
 * Fix build in non-x86 archs.

V2
 * Dropped RFC tag
 * Correctly separated Sean's ucall patches into 2 as originally
   intended.
 * Addressed andrew.jones@ in ucall patches.
 * Fixed ucall pool usage to work for other archs

V1
 * https://lore.kernel.org/all/20220715192956.1873315-1-pgonda@google.com/
