The quilt patch titled Subject: init/Kconfig: lower GCC version check for -Warray-bounds has been removed from the -mm tree. Its filename was init-kconfig-lower-gcc-version-check-for-warray-bounds.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: Kees Cook keescook@chromium.org Subject: init/Kconfig: lower GCC version check for -Warray-bounds Date: Fri, 23 Feb 2024 09:08:27 -0800

We continue to see false positives from -Warray-bounds even in GCC 10, which is getting reported in a few places[1] still:

security/security.c:811:2: warning: `memcpy' offset 32 is out of the bounds [0, 0] [-Warray-bounds]

Lower the GCC version check from 11 to 10.
