+Subject: [PATCH] kbuild: extract modules.builtin.modinfo from vmlinux.o
+
+Partially reverse https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-6.18.y&id=39cfd5b12160be4f57df1c3ba60139741c827616
+to prevent generation of empty modules.builtin.modinfo and modules.builtin
+files that cause modules compilation errors.
+If an out-of-tree package or any kernel-install rule ran modprobe xyz while
+the build was still in progress, and xyz had been configured =y, a clean tree
+would already have xyz listed in modules.builtin; with the empty file produced
+by the buggy rule it was missing, so modprobe emitted "module xyz not found"
+even though the code was sitting inside the freshly built vmlinux.
