Hi Sedat - I pulled these configs from the running systems, but I used 
"make olddefconfig" on these working 5.18 configs to generate the 
corresponding 5.19 configs that failed to boot.  I'll see if I can go 
back in and repeat this process to regen the 5.19 configs (I deleted it 
all after 5.19 failed to boot).

Hi Masahiro, I'm sorry to raise this after release but this seems to be
broken on SOME architectures.  So far I have tested:

Affected - sparc, alpha
Unaffected - riscv, ia64

What do you mean by "release"?

Checking the kernel-version from your paste-URLs:

# Automatically generated file; DO NOT EDIT.
# Linux/sparc64 5.18.16-gentoo Kernel Configuration

# Automatically generated file; DO NOT EDIT.
# Linux/alpha 5.18.15-gentoo Kernel Configuration

# Automatically generated file; DO NOT EDIT.
# Linux/riscv 5.19.0-gentoo Kernel Configuration

# Automatically generated file; DO NOT EDIT.
# Linux/ia64 5.19.0-gentoo Kernel Configuration

Maybe you should try "Affected - sparc, alpha" with Linux v5.19.0
instead of 5.18.x :-)?

-Sedat-

The affected systems are unable to load modules, similar to the
previously reported issue.  All module loading fails with "disagrees
about version of symbol module_layout".

Bisect blames 7b4537199a4a8480b8c3ba37a2d44765ce76cd9b, but this does
not revert cleanly.  Presumably CONFIG_MODVERSIONS=n would fix, but 
this
is a pretty core feature.

Unlike the issue Sedat reported, this is on a GNU toolchain, no clang
involved.

Here are the configs I am using (with make olddefconfig on upgrade to
5.19):

Broken - sparc - https://dpaste.com/5A8F2JD6U
Broken - alpha - https://dpaste.com/FYKK23L9X
Working - riscv - https://dpaste.com/HV6Y4V6NT
Working - ia64 - https://dpaste.com/HDLDNEAK4

Please let me know if there's anything I can do to help track down this
regression.

This is the third batch of cleanups in this development cycle.

This series is available at
git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git
  lto-cleanup-v6

quoted

Changes in v6:
  - Fix false-positive warnings when CONFIG_TRIM_UNUSED_KSYMS=y

Changes in v5:
  - Fix the build error when CONFIG_DEBUG_INFO_BTF=y (reported by
Nathan)
  - Clean up arch/m68k/include/asm/export.h (Nick)
  - Keep gen_symversions (and will be removed by a later patch)
  - Add more comments in the script

Changes in v4:
  - Rename .vmlinux-symver.c to .vmlinux.export.c
    because I notice this approach is useful for further cleanups,
    not only for modversioning but also for overall EXPORT_SYMBOL.
  - New patch
  - New.
    Resent of my previous submission.
