FWIW: Having watched the discussion about CONFIG_ANDROID, it occurs to
me that there's an alternative for WireGuard that sidesteps the issue.
From the last patcheset, it seems that the only use in WireGuard is to
avoid clearing keys on every wake-up.
So: Why not timestamp key-clear events, an

There are numerous presentations and threads galore on why WireGuard
doesn't do knobs. Not worth rehashing here; it's not
Systems that initiate frequent suspend/resume from userspace
can make the kernel aware by enabling PM_USERSPACE_AUTOSLEEP

This allows for certain sleep-sensitive code (wireguard/rng) to
decide on what preparatory work should be performed (or not) in
their pm_notification callbacks.
