In menuconfig / is a shortcut to a find utility into which entering
config_proc_page_monitor takes one to a help page with the following
info:

Symbol: PROC_PAGE_MONITOR [=y]
Prompt: Enable /proc page monitoring 
   Defined at fs/proc/Kconfig:61 
   Depends on: PROC_FS && MMU && EMBEDDED 
   Location:

       -> Pseudo filesystems> 
         -> /proc file system support (PROC_FS [=y]
