The kvfree_rcu() and kfree_rcu() APIs are hazardous in that if you forget the second argument, it works, but might sleep. This sleeping can be a correctness bug from atomic contexts, and even in non-atomic contexts it might introduce unacceptable latencies. This commit therefore removes the single-argument kvfree_rcu() and kfree_rcu() macros. Code that would have previously used these single-argument kvfree_rcu() and kfree_rcu() macros should instead use kvfree_rcu_mightsleep() or kfree_rcu_mightsleep().
