We see new warnings here too, on Ar64, Arm32, x86, i386, MIPS, PowerPC, RISC-V, System/390, SuperH, SPARC, ARC, on multiple combinations of toolchain and kernel configs.

   /builds/linux/kernel/printk/printk.c:261:13: warning: 'panic_in_progress' defined but not used [-Wunused-function]

Bisection points to:

   commit 290ee7858f46d6f007150bcd90cee321cabb8545
   Author: Stephen Brennan <stephen.s.brennan@...cle.com>
   Date:   Wed Feb 2 09:18:18 2022 -0800

       printk: Add panic_in_progress helper
       
       [ Upstream commit 77498617857f68496b360081dde1a492d40c28b2 ]

Reverting that commit makes the warning disappear.

Reproducer:

   tuxmake --runtime podman --target-arch x86_64 --toolchain gcc-12 --kconfig allnoconfig
