The two patchsets have some overlap, so it's good to find a design that
fits both.

I think it's the same. One "-numa mem" option = one "-device dimm"
option; both define one range. Unused memory ranges may remain if you
stumble upon a unusable range such as the PCI window. For example two
"-numa mem,size=2G" options would allocate memory from 0 to 2G and from
4 to 6G.
I'm snipping the rest of the email because I hope this covers all your
doubts.
