Found this in numa-introduce-numa_mem_id-effective-local-memory-node-id.patch:

+#ifndef cpu_to_mem
+#define cpu_to_mem(cpu)                (void)(cpu),0)
+#endif

The resulting paren mismatch causes an error cascade in 2 other patches:

numa-in-kernel-profiling-use-cpu_to_mem-for-per-cpu-allocations.patch

causes build errors:

  CC      kernel/profile.o
