Sorry for the slow turnaround testing this.
This version seems to do better with my quirky system.
Summary of /proc/zoneinfo now looks like this:
$ ./zoneinfo
Node Normal Movable DMA DMA32
0 17090.04 85687.43 14.93 1677.41
1 17949.70 81490.98
2 17911.66 85675.00
3 17936.42 85313.32
which gets close to the mirror numbers reported in early part of boot:
[ 0.000000] efi: Memory: 81050M/420096M mirrored memory
SUM(Normal) = 70887.82
There are ~8GB of "struct page" allocated from boot time allocator,
which covers most of the difference in the values.
