Hi Oliver,

Thanks so much for this, could you give the below a try? I've not tried to
seriously test it locally yet, so it'd be good to set your test machines on
it.

If this doesn't help it suggests call stack/branching might be a thing here
in which case I have other approaches I can take before we have to
duplicate this code.

This patch is against the mm-unstable branch in Andrew's tree [0] but
hopefully should apply fine to Linus's too.

Thanks again!

Best, Lorenzo
