I think all of these markings should be removed instead.
Why are these useful?
It seems many of these filenames in power.h aren't correct anyway.

For instance power.h has:

   /* kernel/power/hibernate.c */
   extern int swsusp_check(void);
   extern void swsusp_free(void);
   extern int swsusp_read(unsigned int *flags_p);
   extern int swsusp_write(unsigned int flags);
   extern void swsusp_close(fmode_t);
   #ifdef CONFIG_SUSPEND
   extern int swsusp_unmark(void);
   #endif

but:

swsusp_check is in swap.c
swsusp_free is in snapshot.c
swsusp_read is in swap.c

etc...

Perhaps:
