In the meantime commit d6c6ae9b71ad ("userfaultfd: buildsystem
activation") added config USERFAULTFD here in linux-next, pushing
PCI_QUIRKS out of the menu.
USERFAULTFD defaults to 'y'. Perhaps it was intended to make (its
prompt) visible only if EXPERT is set. Andrea, Pavel, Andrew?

Anyhow, applied cleanly with d6c6ae9b71ad reverted.
I had to jump through some hoops to convince myself the patch really
only moves some lines around (except for the added source statement).
There's no git diff option that could have helped me here, is there?
I'm sure we'll figure out a way to handle config USERFAULTFD, so
