From bdc9c3e5ed953441a46ef3acd81c783d591c9a96 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 9 Jul 2018 21:07:21 +0900 Subject: x86/build: Remove old -funit-at-a-time GCC quirk The following commit: e501ce957a78 ("x86: Force asm-goto") ... bumped the minimum GCC version to 4.5 for building the x86 kernel. arch/x86/Makefile no longer needs to take care of older GCC versions, such as this pre-4.0 -funit-at-a-time quirk.
