This isn't a fix for the existing code, AFAICT the issue here is that
ARCH_MMP is currently only available for arm and presumably something in
the rest of your series makes it available for arm64.  This would be a
prerequisite for that patch.

Please don't just insert random fixes tags just because you can.
