I only saw this now, seems I wasn't copied... I'll take a deeper look, but

Thanks for taking a look. I'll make sure you are copied on the updates.

I have a couple of meta comments:

• This could arguably go in the security book rather than the admin guide. I don't really have a strong opinion on which is right at the moment, but others might.

Since l1tf.rst is already here in admin guide, that's why I keep spectre.rst here as well.

I believe l1tf is misplaced. That one really is Intel-specific (not even all x86s are affectd). Same for Meltdown. Pavel
