From e5f95c8b7700a7bf1c2d24eedc677954d9aa0285 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sat, 2 Feb 2008 18:57:18 +0100 Subject: kbuild: print only total number of section mismatces found We have too many section mismatches detected at the moment. So silence modpost and prevent the option from being set in a typical allyesconfig build. Tell the user how to see all the deteils in the summary message from modpost.
