From eeeda4cd06e828b331b15741a204ff9f5874d28d Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Wed, 24 Sep 2014 13:30:12 +0100 Subject: [PATCH 1/1] x86/relocs: Make per_cpu_load_addr static per_cpu_load_addr is only used for 64-bit relocations, but is declared in both configurations of relocs.c - with different types. This has undefined behaviour in general. GNU ld is documented to use the larger size in this case, but other tools may differ and some warn about this.
