I don't feel brave enough to take a series affecting all architectures
so late in the game, and the whole thing had very little arm64
exposure. The latest QEMU doesn't seem to work anymore, so I don't
have any MTE-capable emulation (and using the FVP remotely is a pain
in the proverbial neck).

I'll come back to this after the merge window, should Peter decide to
respin the series.

Thanks,
