Yes it would. Below is the incremental patch to the end of the series,
which I will fold appropriately back into a precursor to do the refactor
and then this patch adding the rootdelay (nb I fixed the spacing you
complained about elsewhere while I was here).
Are you OK with me keeping your ack on this one once updated? It would
be essentially either of the two current hunks applied to the new
function instead.
BTW, another side effect is adding "ro" in the Xen case, which I think
was a bug to omit until now, I'll find an appropriate place to fix that.
Ian.
