From 36bf9da2913054c218337d8cd7cb11bddc1fafb0 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 27 Aug 2018 14:45:14 +0900 Subject: x86/build: Remove jump label quirk for GCC older than 4.5.2 Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6") bumped the minimum GCC version to 4.6 for all architectures. Remove the workaround code. It was the only user of cc-if-fullversion. Remove the macro as well. Signed-off-by: Masahiro Yamada Signed-off-by: Thomas Gleixner Cc: "H.
