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



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.
