From 6aa69043d9f3f4adc5b3817ccfcac1fddfe10ded Mon Sep 17 00:00:00 2001 From: =?utf8?q?Daniel=20D=C3=ADaz?= Date: Wed, 21 Feb 2018 12:07:57 -0600 Subject: [PATCH] selftests/intel_pstate: Fix build rule for x86 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Ensure that ARCH is defined and that this only builds for x86 architectures. It is possible to build from the root of the Linux tree, which will define ARCH, or to run make from the selftests/ directory itself, which has no provision for defining ARCH, so this change is to use the current definition (if any), or to check uname -m if undefined.
