From 9c8bb3eac07de8834d012e12ff0185a9dcc01331 Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Thu, 14 Jan 2021 16:32:42 -0600 Subject: objtool: Don't fail the kernel build on fatal errors [ Upstream commit 655cf86548a3938538642a6df27dd359e13c86bd ] This is basically a revert of commit 644592d32837 ("objtool: Fail the kernel build on fatal errors"). That change turned out to be more trouble than it's worth. Failing the build is an extreme measure which sometimes gets too much attention and blocks CI build testing. These fatal-type warnings aren't yet as rare as we'd hope, due to the ever-increasing matrix of supported toolchains/plugins and their fast-changing nature as of late. Also, there are more people (and bots) looking for objtool warnings than ever before, so even non-fatal warnings aren't likely to be ignored for long.
