However x86/urgent (at least as visible [1]) doesn't contain anything from
this series, and x86/mm has everything except "Fix effective RW computation".

But tip/urgent does merge x86/mm so hopefully it means it's really going to
Linus now-ish (and not next merge window)? It just doesn't have "urgent" in
the branch name?

So that means adding it to x86/mm after the current one is sent as urgent?

Just wanted to double check, thanks.
