[GIT PULL] arm64 fixes for -rc4

[Will Deacon]

Hi Linus,

Here's a sizeable batch of Friday the 13th arm64 fixes for -rc4.
What could possibly go wrong?

The obvious reason we have so much here is because of the holiday season
right after the merge window, but we've also brought back an erratum
workaround that was previously dropped at the last minute and there's an
MTE coredumping fix that strays outside of the arch/arm64 directory.

Anyway, it's all been in -next, the CI robots seem happy enough and
there's the usual summary in the tag.

Please pull.

Cheers,

Will
