Hi,

I think I'll have to renege on that timeline.

I'm not entirely happy with how the gap calculation is currently done and 
I'm planning on reworking the patch almost completely to be based on the 
existing loop in pbus_size_mem() but I'll have to first move that loop 
into own function (for which I have a patch in another series anyway so 
the more itself is just about shuffling my existing patches).

It'll take a few days more.
