Well, this is what I expected, we do not support this feature for
ARCH_NEEDS_WEAK_PER_CPU (alpha and s390 with CONFIG_SMP=y &&
CONFIG_MODULE=y).
Unfortunately ARCH_NEEDS_WEAK_PER_CPU is not a config option, so I
can't add it as a dependency for CONFIG_MEM_ALLOC_PROFILING. Should I
handle this differently?

Make it a config option? That would be a cleanup on its own.

I'll take a stab at it. Thanks!
