The new migration test uncovered some alignment problems in the s390x
code:
https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03012.html
Here are some patches to fix these issues (only tested with
clang and -fsanitize=undefined, since I do not have access to
a Sparc machine, but I hope that covers the issues there, too).
v2:
- Use static assert with offsetof in the first patch instead of comments
- Use stw_be_p in the second patch and add a comment about SA22-7204
