+Contact:        David Brownell <dbrownell@users.sourceforge.net>
+Description:
+  As a Kconfig option, individual GPIO signals may be accessed from
+  userspace.  GPIOs are only made available to userspace by an explicit
+  "export" operation.  If a given GPIO is not claimed for use by
+  kernel code, it may be exported by userspace (and unexported later).
+  Kernel code may export it for complete or partial access.
+  GPIOs are identified as they are inside the kernel, using integers in
+  the range 0..INT_MAX.  See Documentation/gpio.txt for more information.

+        /export ... asks the kernel to export a GPIO to userspace
+        /unexport ... to return a GPIO to the kernel
+        /gpioN ... for each exported GPIO #N

+          This is the generic IDE driver.  This driver attaches to the
+          fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
+          so on).  Please note that if this driver is built into the
+          kernel or loaded before other ATA (IDE or libata) drivers
+          and the controller is located at legacy ports, this driver
+          may grab those ports and thus can prevent the controller
+          specific driver from attaching.
+          Also, currently, IDE generic doesn't allow IRQ sharing
+          meaning that the IRQs it grabs won't be available to other
+          controllers sharing those IRQs which usually makes drivers
+          for those controllers fail.  Generally, it's not a good idea
+          to load IDE generic driver on modern systems.
          If unsure, say N.
