From aeafd623f866c429307e3a4a39998f5f06b4f00e Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Tue, 6 Dec 2016 14:18:51 +0100 Subject: [PATCH] perf tools: Move headers check into bash script To make it nicer and easily maintainable. Also moving the check into fixdep sub make, so its output is not scattered around the build output. Removing extra $$ from mman*.h checks.
