    arch/um: make it work with defconfig and x86_64 · e40f04d0

    arch/um/defconfig only lists one default configuration, and that applies
    only to the i386 architecture.  Replace it with two minimal
    configuration files generated using `make savedefconfig`:
      i386_defconfig and x86_64_defconfig
    The build scripts now require two updates:
    1. um's Kconfig (arch/x86/um/Kconfig) should specify an ARCH_DEFCONFIG
       section explicitly pointing to these scripts if the required
       variables are set.  Take care to remove the DEFCONFIG_LIST section
       defined in the included file arch/um/Kconfig.common.
    2. um's Makefile (arch/um/Makefile) should set KBUILD_DEFCONFIG properly
       for the top-level Makefile to pick up.  Copy the logic in
       arch/x86/Makefile to properly pick the defconfig file depending on
       the actual architecture; except we're working with $SUBARCH here,
       instead of $ARCH.
    Now, you can do:
      $ ARCH=um make defconfig
      $ ARCH=um make
    and successfully build User-Mode Linux on an x86_64 box in default
