We plan keeping sk->sk_forward_alloc as small as possible in future patches. This means we are going to call sk_memory_allocated_add() and sk_memory_allocated_sub() more often. Implement a per-cpu cache of +1/-1 MB, to reduce number of changes to sk->sk_prot->memory_allocated, which would otherwise be cause of false sharing.
