[RFC PATCH 0/4] KVM selftests for s390x

[Thomas Huth <thuth@redhat.com>]

This patch series enables the KVM selftests for s390x. As a first
test, the sync_regs from x86 has been adapted to s390x.

Please note that the ucall() interface is not used yet - since
s390x neither has PIO nor MMIO, this needs some more work first
before it becomes usable (we likely should use a DIAG hypercall
here, which is what the sync_reg test is currently using, too...).

Thomas Huth (4):
  KVM: selftests: Guard struct kvm_vcpu_events with
    __KVM_HAVE_VCPU_EVENTS
  KVM: selftests: Align memory region addresses to 1M on s390x
  KVM: selftests: Add processor code for s390x
  KVM: selftests: Add the sync_regs test for s390x
