Hi Laurent,
We merged SPF v11 and some patches from v12 into our platforms. After
several experiments, we observed SPF has obvious improvements on the

setup_kup() is used by both 64-bit and 32-bit code. However on 64-bit
it must not be __init, because it's used for CPU hotplug, whereas on
32-bit it should be __init because it calls setup_kuap/kuep() which
are __init.
We worked around that problem in the past by marking it __ref, see
