Could we merge it? I'm juggling a bunch of different things and prone to lose track of something :\ I'll need to drum up a bit of interest to review the QEMU fixes from those who know the code too, so that may take some time. I left it out of arm unittests.cfg entirely, and s390 and powerpc seems to work by luck enough to be useful for gitlab CI so I don't think there is a chnage needed really unless you're paranoid. I do have a later patch that adds a memory tester that does trigger it right away on powerpc. I'll send that out after this series is merged... but we do still have the issue that the gitlab CI image has the old QEMU don't we? Until we update distro. Thanks, Nick
