Good catch :).
BTW how this happen? hot-unplug on lpar?
Maybe add brief note about it into commit message.

nit: I'd personally do:
f="/sys/devices/system/node/has_high_memory"
[ -f "$f" ] || f="/sys/devices/system/node/has_normal_memory"
N_NODES="$(cat $f | tr ',' ' ')"
but that's a tiny detail.
It'd be great to rewrite these tests into C.
Kind regards,
Petr
