OK, I might be missing some of the patch. My net/ipv4/fib_semantics.c
looks like this (from line 601 to 615):
new_info_hash = fib_hash_alloc(bytes);
new_laddrhash = fib_hash_alloc(bytes);
if (!new_info_hash || !new_laddrhash) {
fib_hash_free(new_info_hash, bytes);
fib_hash_free(new_laddrhash, bytes);
} else {
memset(new_info_hash, 0, bytes);
memset(new_laddrhash, 0, bytes);
fib_hash_move(new_info_hash, new_laddrhash,
new_size);
}

if (!fib_hash_size)
goto failure;
}

...and after rebuilding the kernel, I still get the following (similar,
but different) error on boot:
