Hi Linus,

Although we're still debugging a few minor arm64-specific issues in
mainline, I didn't want to hold this lot up in the meantime. We've got
an additional KASLR fix after the previous one wasn't quite complete, a
fix for a performance regression when mapping executable pages into
userspace and some fixes for kprobe blacklisting. All candidates for
stable and summarised in the tag.

Please pull. Thanks,
