* fix a virtual-physical confusion in mvpg-sie
* pick up Janoschs r-bs

Some environments on s390x require guests to be aligned to 2GB. This is a
problem when kvm-unit-tests act as a hypervisor, since guests run with MSO/MSL
there and guest memory doesn't satisfy this requirement.

This series ensures kvm-unit-tests fulfills the 2G alignment requirement.

Note that these changes make mvpg-sie test case fail under KVM due to a bug in
prefix handling, a fix is was submitted here:

Nico Boehr (3):
  s390x: spec_ex-sie: refactor to use snippet API
  s390x: sie: ensure guests are aligned to 2GB
  s390x: mvpg-sie: fix virtual-physical address confusion
