Thanks, Stephen.

Paul, Palmer -- If it's not too late, then it would probably be best to
stick this commit (60c1b220d8bc) and any dependencies on their own stable
branch so that we can both pull it into our respective trees and I can
resolve this conflict in the arm64 tree, which I'll send early during the
merge window.

Looking at your tree, I guess I could just pull in
common/for-v5.4-rc1/cpu-topology if you promise never to rebase it. Failing
that, you could fork a new branch from 60c1b220d8bc and I could just pull
that part instead.

Please let me know.
