Ron,
'Scuse my ignorance,

yes, or more aggressive: OS remaps virtual memory and then removes that
physical memory from the maps. I mean, if the DIMM with your kernel is
bad, it's all over; but if it is some other DIMM, well, maybe it won't
be too hard. Or maybe it will.
Needed for hot plug memory and xen.
Also, the memory rmap needs rewriting anyway; here's a chance to get
this done.
Also, there's not enough kernel discussion on this list (as per the town
meeting log). So I am trying to incite some.
