Merge tag 'core-bugs-2025-12-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull bug handling infrastructure updates from Ingo Molnar:
"Core updates:
- Improve WARN(), which has vararg printf like arguments, to work
with the x86 #UD based WARN-optimizing infrastructure by hiding the
format in the bug_table and replacing this first argument with the
address of the bug-table entry, while making the actual function
that's called a UD1 instruction (Peter Zijlstra)
- Introduce the CONFIG_DEBUG_BUGVERBOSE_DETAILED Kconfig switch (Ingo
Molnar, s390 support by Heiko Carstens)
Fixes and cleanups:
- bugs/s390: Remove private WARN_ON() implementation (Heiko Carstens)
- <asm/bugs.h>: Make i386 use GENERIC_BUG_RELATIVE_POINTERS (Peter
Zijlstra)"
