From 63fea0af43af5beb3779fd2cae078d5d77b4bb11 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 12 Nov 2018 11:35:20 +0900 Subject: x86, powerpc: Remove -funit-at-a-time compiler option entirely GCC 4.6 manual says: -funit-at-a-time This option is left for compatibility reasons. -funit-at-a-time has no effect, while -fno-unit-at-a-time implies -fno-toplevel-reorder and -fno-section-anchors. Enabled by default. Remove it. Signed-off-by: Masahiro Yamada Signed-off-by: Borislav Petkov Acked-by: Ingo Molnar Acked-by: Michael Ellerman Cc: "H.
