Wait a minute. You're now arguing about whether the generic "x86" means i386 or x86_64. Its meaning is already defined in arch/x86/Kconfig and arch/x86/um/Kconfig: see the config 64BIT. Unless i386 is explicitly specified, the default is to build a 64-bit kernel. That is already defined for a normal Linux kernel, and user-mode Linux should not break that convention. So, in the example you pulled out of your hat: $ make defconfig ARCH=um SUBARCH=x86 the user should expect a 64-bit build, and not an i386 build as you say. Both my patches are correct, and the "regression" that you pointed out is a red herring.
