PowerISA 3.0 makes several changes to not only the format of the HPT but also the behavior surrounding it. For instance, TLBIE no longer requires serialization. Removing this lock cuts buildworld time in half on a 18-core/72-thread POWER9 system, demonstrating that this lock is highly contended on such a system. There was odd behavior observed trying to make this change in a backwards-compatible manner in moea64_native.c, so the best option was to fully split it, and largely revert the original changes adding POWER9 support to the original file.
