From 09155120cf0ffe6f0c8aba3aa625831405b65996 Mon Sep 17 00:00:00 2001 From: Michal Marek Date: Thu, 17 Jun 2010 15:14:58 +0200 Subject: kbuild: Clean up and speed up the localversion logic Now that we run scripts/setlocalversion during every build, it makes sense to move all the localversion logic there. This cleans up the toplevel Makefile and also makes sure that the script is called only once in 'make prepare' (previously, it would be called every time due to a variable expansion in an ifneq statement). No user-visible change is intended, unless one runs the setlocalversion script directly.
