The quilt patch titled
Subject: panic: hide unused global functions
has been removed from the -mm tree. Its filename was
panic-hide-unused-global-functions.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
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: panic: hide unused global functions
Date: Wed, 17 May 2023 15:10:55 +0200
Building with W=1 shows warnings about two functions that have no
declaration or caller in certain configurations:
kernel/panic.c:688:6: error: no previous prototype for 'warn_slowpath_fmt' [-Werror=missing-prototypes]
kernel/panic.c:710:6: error: no previous prototype for '__warn_printk' [-Werror=missing-prototypes]
Enclose the definition in the same #ifdef check as the declaration.
