A section name for .data..ro_after_init was added by both:

    commit d07a980c ("s390: add proper __ro_after_init support")

and

    commit d7c19b06 ("mm: kmemleak: scan .data.ro_after_init")

The latter adds incorrect wrapping around the existing s390 section, and
came later.  I'd prefer the s390 naming, so this moves the s390-specific
name up to the asm-generic/sections.h and renames the section as used by
kmemleak (and in the future, kernel/extable.c).
