From 41f30914fc33116cfd0fd0982c8effe435d97698 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sun, 27 Jan 2019 13:44:29 +0100 Subject: perf map: Move structs and prototypes for map groups to a separate header And since machine.h only needs what is in there, make it stop including map.h and instead include this newly introduced map_groups.h instead.
