Looks good to me. Your patch fixes the warning emitted earlier by

./scripts/kernel-doc -none mm/page_ext.c
mm/page_ext.c:178: warning: Function parameter or member 'page_ext' not described in 'page_ext_put'

one nit comment on the changelog summary

mm: fix compiler warning with make W=1

Can you make it more specific like "mm/page_exit: fix kernel doc warning in page_ext_put()"

Thanks,
Pavan
