kconfig: extend output of 'listnewconfig'
We at Red Hat/Fedora have generally tried to have a per file breakdown of every config option we set. This makes it easy for us to add new options when they are exposed and keep a changelog of why they were set. A Fedora example is here: https://src.fedoraproject.org/cgit/rpms/kernel.git/tree/configs/fedora/generic Using various merge scripts, we build up a config file and run it through 'make listnewconfig' and 'make oldnoconfig'. The idea is to print out new config options that haven't been manually set and use the default until a patch is posted to set it properly. To speed things up, it would be nice to make it easier to generate a patch to post the default setting. The output of 'make listnewconfig' has two issues that limit us: - it doesn't provide the default value - it doesn't provide the new 'choice' options that get flagged in 'oldconfig' This patch extends 'listnewconfig' to address the above two issues. This allows us to run a script make listnewconfig | rhconfig-tool -o patches; git send-email patches/ The output of 'make listnewconfig': CONFIG_NET_EMATCH_IPT CONFIG_IPVLAN CONFIG_ICE CONFIG_NET_VENDOR_NI CONFIG_IEEE802154_MCR20A CONFIG_IR_IMON_DECODER CONFIG_IR_IMON_RAW The new output of 'make listnewconfig': CONFIG_KERNEL_XZ=n CONFIG_KERNEL_LZO=n CONFIG_NET_EMATCH_IPT=n CONFIG_IPVLAN=n CONFIG_ICE=n CONFIG_NET_VENDOR_NI=y CONFIG_IEEE802154_MCR20A=n CONFIG_IR_IMON_DECODER=n CONFIG_IR_IMON_RAW=n Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
