There were no targets still actively using Linux 5.4.

-Subject: [PATCH] modpost: refactor namespace_from_kstrtabns() to not hard-code
- section name
-
-Currently, namespace_from_kstrtabns() relies on the fact that
-namespace strings are recorded in the __ksymtab_strings section.
-Actually, it is coded in include/linux/export.h, but modpost does
-not need to hard-code the section name.
-
-Elf_Sym::st_shndx holds the index of the relevant section. Using it is
-a more portable way to get the namespace string.
-
-Make namespace_from_kstrtabns() simply call sym_get_data(), and delete
-the info->ksymtab_strings .
-
-While I was here, I added more 'const' qualifiers to pointers.
