v1->v2:
---
* cmm lib: return struct instead of passing in a pointer (thanks Claudio)
* cmm lib: remove get_page_addr() (thanks Claudio)
* cmm lib: print address of mismatch (thanks Claudio)
* cmm lib: misc comments reworked, added and variables renamed
* make sure page states change on every iteration (thanks Claudio)
* add WRITE_ONCE even when not strictly needed (thanks Claudio)

Add a test which changes CMM page states while VM is being migrated.

Nico Boehr (2):
  s390x: add a library for CMM-related functions
  s390x: add CMM test during migration
