From e40f04d040c66d8312ecfaf6091b2da78531276c Mon Sep 17 00:00:00 2001 From: Ramkumar Ramachandra Date: Fri, 27 Sep 2013 09:44:46 +0530 Subject: 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.
