Merge branch 'net-three-additions-to-net_hotdata'

Eric Dumazet says:

====================
net: three additions to net_hotdata

This series moves three fast path sysctls to net_hotdata.

To avoid <net/hotdata.h> inclusion from <net/sock.h>,
create <net/proto_memory.h> to hold proto memory definitions.
