The quilt patch titled Subject: kcsan: avoid passing -g for test has been removed from the -mm tree. Its filename was kcsan-avoid-passing-g-for-test.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

------------------------------------------------------ From: Marco Elver elver@google.com Subject: kcsan: avoid passing -g for test Date: Thu, 16 Mar 2023 23:47:05 +0100

Nathan reported that when building with GNU as and a version of clang that defaults to DWARF5, the assembler will complain with:

Error: non-constant .uleb128 is not supported

This is because `-g` defaults to the compiler debug info default. If the assembler does not support some of the directives used, the above errors occur. To fix, remove the explicit passing of `-g`.

All the test wants is that stack traces print valid function names, and debug info is not required for that. (I currently cannot recall why I added the explicit `-g`.)
