+config PROC_FS
+        bool "/proc file system support" if EMBEDDED
+        default y
+        help
+          This is a virtual file system providing information about the status
+          of the system. "Virtual" means that it doesn't take up any space on
+          your hard disk: the files are created on the fly by the kernel when
+          you try to access them. Also, you cannot read the files with older
+          version of the program less: you need to use more or cat.
+
+          It's totally cool; for example, "cat /proc/interrupts" gives
+          information about what the different IRQs are used for at the moment
+          (there is a small number of Interrupt ReQuest lines in your computer
+          that are used by the attached devices to gain the CPU's attention --
+          often a source of trouble if two devices are mistakenly configured
+          to use the same IRQ). The program procinfo to display some
+          information about your system gathered from the /proc file system.
+
+          Before you can use the /proc file system, it has to be mounted,
+          meaning it has to be given a location in the directory hierarchy.
+          That location should be /proc. A command such as "mount -t proc proc
+          /proc" or the equivalent line in /etc/fstab does the job.
+
+          The /proc file system is explained in the file
+          <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
+          ("man 5 proc").
+
+          This option will enlarge your kernel by about 67 KB. Several
+          programs depend on this, so everyone should say Y here.
+
+config PROC_KCORE
+        bool "/proc/kcore support" if !ARM
+        depends on PROC_FS && MMU
+
+config PROC_VMCORE
+        bool "/proc/vmcore support (EXPERIMENTAL)"
+        depends on PROC_FS && CRASH_DUMP
+        default y
+        help
+        Exports the dump image of crashed kernel in ELF format.
+
+config PROC_SYSCTL
+        bool "Sysctl support (/proc/sys)" if EMBEDDED
+        depends on PROC_FS
+        select SYSCTL
+        default y
+        ---help---
+          The sysctl interface provides a means of dynamically changing
+          certain kernel parameters and variables on the fly without requiring
+          a recompile of the kernel or reboot of the system.  The primary
+          interface is through /proc/sys.  If you say Y here a tree of
+          modifiable sysctl entries will be generated beneath the
+          /proc/sys directory. They are explained in the files
+          in <file:Documentation/sysctl/>.  Note that enabling this
+          option will enlarge the kernel by at least 8 KB.
+
+          As it is generally a good thing, you should say Y here unless
+          building a kernel for install/rescue disks or your system is very
+          limited in memory.
