| |
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
