OK, so I pushed:
  origin/users/jslaby/stable/lto
  origin/users/jslaby/stable/lto-base
  origin/users/jslaby/stable/lto-disabled

lto-base is base for both, lto-disabled is the same as lto, but config.

Then I compiled the lto one on 15sp3 using gcc-12 and booted successfully on
15sp4.

The patches are not that easy backportable, so using them on anything older
(like 15sp4 kernel) creates a lot of conflicts. I.e. all the above is based on
the stable branch (5.18).
