From 4760fe26c72563d284cd620421dc8196006ce5e3 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sun, 22 Apr 2018 10:20:50 -0400 Subject: [PATCH] Makefile: Update clang warning disables from Linux Re-sync the logic about which clang warnings to disable from v4.17-rc1. Note that we don't disable all of the same ones as for now we haven't run into any cases of warnings from clang in code from upstream Linux.
