Greetings, The pmap in armv4/5 has been broken for years at this point. It basically works, but has issues with unaligned buffers. Since these have remained unfixed for a long time, and most of the main ARM developers have given up trying to fix it, I think it would be best to retire the support rather than waste people's time that seem to be working only to discover after a lot of effort that it's busted. Since the consensus at the FreeBSD developer's summit appeared to be 'let's let it go'. It would remove the TARGET_ARCH arm and armeb. armv6 would remain unaffected (though see a parallel thread).
