Eric Dumazet 3cd3399dd7 net: implement per-cpu reserves for memory_allocated ...

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.
