[V3 00/11] KVM: selftests: Add simple SEV test

[Peter Gonda <pgonda@google.com>]

This patch series combines the work Michael Roth has done in supporting
SEV guests in selftests and the work Sean Christopherson suggested to
allow ucalls from SEV guests. And the work Sean has sent to consolidate
the ucall boilerplate code. Along with a very simple version of the
SEV selftests Michael originally proposed.

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/
