Hmm... The problem is the "addresses" of per-cpu symbols are faked: they are actually offsets from $r21. So we can't just load such an offset with PCALA addressing.
It looks like we'll need to introduce an attribute for GCC to make an variable "must be addressed via GOT", and add the attribute into PER_CPU_ATTRIBUTES.
