[PATCH 0/2] objtool: Add option to fail build on vmlinux warnings
From: Brendan Jackman
Date: Fri Dec 13 2024 - 06:32:11 EST
This adds an option to objtool to exit with an error when it enounters
warnings.
Then, it adds a config to enable that flag on vmlinux. This enables you
to fail the build e.g. when noinstr is violated.
