This adds the very basic infrastructure for s390x. For now, only a basic self test is provided. This one will also run under TCG. The following, previously sent patches are required: - [PATCH kvm-unit-tests] Makefile: drop "-lpthread -lrt" - [kvm-unit-tests PATCH v1 0/3] provide asm-generic spinlock - [kvm-unit-tests PATCH v1] lib: fix compilation warning Parts taken from a prototype by Thomas Huth.
