This patch prepares the ground for further extension of
/proc/pid/fd[info] handling code by moving fdinfo handling
code into fs/proc/fd.c.

I think such move makes both fs/proc/base.c and fs/proc/fd.c
easier to read.

BTW, looking at the other stuff in fs/proc/base.c, why the hell is
struct file * grabbed in proc_map_files_readdir()?  All we do with
it is passing it to proc_fill_cache(), which passes it to
proc_map_files_instantiate(), which looks at two sodding bits
in file->f_mode.  Then we go and fput() all those struct file
references we'd been putting into the array...  What for?
