From 5a4630aadb9a9525474e9ac92965829f990cb5c4 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Mon, 17 Sep 2018 17:07:54 +0930 Subject: ftrace: Build with CPPFLAGS to get -Qunused-arguments When building to record the mcount locations the kernel uses KBUILD_CFLAGS but not KBUILD_CPPFLAGS. This means it lacks -Qunused-arguments when building with clang, resulting in a lot of noisy warnings.
