From 7ab44e9ee5f241c0ed19e350d17e80bd90bde93d Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Mon, 16 Aug 2021 17:21:07 -0700 Subject: x86: remove cc-option-yn test for -mtune= As noted in the comment, -mtune= has been supported since GCC 3.4. The minimum required version of GCC to build the kernel (as specified in Documentation/process/changes.rst) is GCC 4.9. tune is not immediately expanded. Instead it defines a macro that will test via cc-option later values for -mtune=. But we can skip the test whether to use -mtune= vs. -mcpu=.
