Subject: perf map: Add const to map_ip and unmap_ip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Functions purely determine a value from the map and don't need to modify
it. Move functions to C file as they are most commonly used via a
function pointer.
