Hi Linus,

Another handful of arm64 fixes here. Most of the complication comes from
improving our kpti code to avoid lengthy pauses (30+ seconds) during boot
when we rewrite the page tables. There are also a couple of IORT fixes
that came in via Lorenzo. Usual summary in the tag.

Please pull,

Thanks,

Will
