So, maybe my merge resolutions were not sufficient, because that then
failed to build (powerpc ppc64_defconfig):
mm/slab_common.c: In function 'create_cache':
mm/slab_common.c:238:13: error: 'freeptr_offset' undeclared (first use in this function); did you mean 'freeptr_t'?

mm/slab_common.c:238:13: note: each undeclared identifier is reported only once for each function it appears in
mm/slab_common.c: At top level:

So I used the slab tree from next-20240906 for today in the hope that
the duplications will be taken care of and the whole things becomes
clearer.
