- [PATCH 12/12] tests/tcg/s390x: Test unaligned accesses

Hi,

This series makes accessing unaligned addresses with branching, LPSWE,
EXECUTE and relative long instructions fail with a specification
exception instead of succeeding.

Patches 1-10 are fixes, patch 11 adjusts a comment to reflect a change
done by fixes, patch 12 adds a number of softmmu and user tests.

Best regards,
Ilya
