The quilt patch titled
Subject: gcov: shut up missing prototype warnings for internal stubs
has been removed from the -mm tree. Its filename was
gcov-shut-up-missing-prototype-warnings-for-internal-stubs.patch
This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: gcov: shut up missing prototype warnings for internal stubs
Date: Tue, 25 Jul 2023 14:23:38 +0200
gcov uses global functions that are called from generated code, but these
have no prototype in a header, which causes a W=1 build warning:
kernel/gcov/gcc_base.c:12:6: error: no previous prototype for '__gcov_init' [-Werror=missing-prototypes]
kernel/gcov/gcc_base.c:40:6: error: no previous prototype for '__gcov_flush' [-Werror=missing-prototypes]
kernel/gcov/gcc_base.c:46:6: error: no previous prototype for '__gcov_merge_add' [-Werror=missing-prototypes]
kernel/gcov/gcc_base.c:52:6: error: no previous prototype for '__gcov_merge_single' [-Werror=missing-prototypes]
Just turn off these warnings unconditionally for the two files that
contain them.
