From 77ab21adae509c5540956729e2d03bc1a59bc82a Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Sat, 8 Feb 2014 09:01:11 +0100 Subject: [PATCH] Kbuild, lto, workaround: Don't warn for initcall_reference in modpost This reference is discarded, but can cause warnings when it refers to exit. Ignore for now. This is a workaround and can be removed once we get rid of -fno-toplevel-reorder Signed-off-by: Andi Kleen Link: http://lkml.kernel.org/r/1391846481-31491-7-git-send-email-ak@linux.intel.com Signed-off-by: H.
