arch/um: make it work with defconfig and x86_64
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
configuration.
