Paolo 'Blaisorblade' Giarrusso b2670eacfb [PATCH] uml: use DEFCONFIG_LIST to avoid reading host's config ... This should make sure that, for UML, host's configuration files are not considered, which avoids various pains to the user. Our dependency are such that the obtained Kconfig will be valid and will lead to successful compilation - however they cannot prevent an user from disabling any boot device, and if an option is not set in the read .config (say /boot/config-XXX), with make menuconfig ARCH=um, it is not set. This always disables UBD and all console I/O channels, which leads to non-working UML kernels, so this bothers users - especially now, since it will happen on almost every machine (/boot/config-`uname -r` exists almost on every machine). It can be workarounded with make defconfig ARCH=um, but it is non-obvious and can be avoided, so please _do_ merge this patch. Given the existence of options, it could be interesting to implement (additionally) "option required" - with it, Kconfig will refuse reading a .config file (from wherever it comes) if the given option is not set. With this, one could mark with it the option characteristic of the given architecture (it was an old proposal of Roman Zippel, when I pointed out our problem): config UML option required default y However this should be further discussed: *) for x86, it must support constructs like: ==arch/i386/Kconfig== config 64BIT option required default n where Kconfig must require that CONFIG_64BIT is disabled or not present in the read .config. *) do we want to do such checks only for the starting defconfig or also for .config? Which leads to: *) I may want to port a x86_64 .config to x86 and viceversa, or even among more different archs. Should that be allowed, and in which measure (the user may force skipping the check for a .config or it is only given a warning by default)?
