From b5064654c538ad9a2eb1195d80e7593b2e1c1452 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 12 Nov 2013 15:08:38 -0800 Subject: scripts/mod/modpost.c: handle non ABS crc symbols For some reason I managed to trick gcc into create CRC symbols that are not absolute anymore, but weak. Make modpost handle this case.
