Dies trying to compile mm/slab.c because something screwed the pooch with
the definition of numa_mem_id(). My bets are on
numa-slab-use-numa_mem_id-for-slab-local-memory-node.patch

Looks like a twisty little maze of cpp macros in each case, probably
related to this:

% grep -i numa .config
# CONFIG_NUMA is not set
