Log Message:
linux: Kludgily make radix tree safe for RCU

Using a lock is completely stupid (gotta be cpu_simple_lock because
there's no radix_tree_destroy or anything), and the nonsense to do
unvolatile/unconst is garbage, but it will serve to make this safe
for RCU until someone makes our radix tree code RCU-safe (which
Someone^TM should totally do).
