module: do percpu allocation after uniqueness check. No, really!
commit 8d8022e8aba85192e937f1f0f7450e256d66ae5c upstream.
v3.8-rc1-5-g1fb9341 was supposed to stop parallel kvm loads exhausting
percpu memory on large machines:
Now we have a new state MODULE_STATE_UNFORMED, we can insert the
module into the list (and thus guarantee its uniqueness) before we
allocate the per-cpu region.
In my defence, it didn't actually say the patch did this. Just that
we "can".
This patch actually *does* it.
