4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Joel Stanley <joel@xxxxxxxxx> 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.
