The quilt patch titled
Subject: s390/traps: only define is_valid_bugaddr() under CONFIG_GENERIC_BUG
has been removed from the -mm tree. Its filename was
s390-traps-only-define-is_valid_bugaddr-under-config_generic_bug.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: s390/traps: only define is_valid_bugaddr() under CONFIG_GENERIC_BUG
Date: Thu, 30 Nov 2023 17:22:33 -0700
When building with -Wmissing-prototypes without CONFIG_GENERIC_BUG, there
is a warning about a missing prototype for is_valid_bugaddr():
arch/s390/kernel/traps.c:46:5: warning: no previous prototype for 'is_valid_bugaddr' [-Wmissing-prototypes]
46 | int is_valid_bugaddr(unsigned long addr)
| ^~~~~~~~~~~~~~~~
The prototype is only declared with CONFIG_GENERIC_BUG, so only define the
function under the same condition to clear up the warning, which matches
other architectures.
