Enable kernel options for Docker

Add a simple option for enabling all the requirements for Docker to run.

Install

1. Create a folder inside your kernel source tree, for example utils, then place the Kconfig in there.
2. Add a line into the root Kconfig: source "utils/Kconfig".

Sample final Kconfig:

#
# For a description of the syntax of this configuration file,
# see Documentation/kbuild/kconfig-language.txt.
#
mainmenu "Linux/$ARCH $KERNELVERSION Kernel Configuration"

config SRCARCH
        string
        option env="SRCARCH"

source "utils/Kconfig"

source "arch/$SRCARCH/Kconfig"

Now enable the Docker support option:

Utilities --->
  [*] Docker support

And you should be good to go. Compile the kernel, install, reboot, enjoy.
