So, remove CONFIG_BASE_FULL and move the config choice to CONFIG_BASE_SMALL (which defaults to 'n') For defconfigs explicitely disabling BASE_FULL, explicitely enable BASE_SMALL. For defconfigs explicitely enabling BASE_FULL, drop it as it is the default. Signed-off-by: Yoann Congal <yoann.congal@...le.fr> --- v4->v5: * Patch refreshed (2/3 changed) * Added defconfigs refresh (Petr Mladek's comment, thanks!) * dropped the redundant "default n" (Masahiro Yamada's comment, thanks!) v3->v4: * Split "switch CONFIG_BASE_SMALL to bool" and "Remove the redundant config" (this patch) into two patches * keep CONFIG_BASE_SMALL instead of CONFIG_BASE_FULL --- arch/arm/configs/collie_defconfig | 2 +- arch/arm/configs/keystone_defconfig | 2 +- arch/arm/configs/lpc18xx_defconfig | 2 +- arch/arm/configs/moxart_defconfig | 2 +- arch/arm/configs/mps2_defconfig | 2 +- arch/arm/configs/omap1_defconfig | 2 +- arch/arm/configs/stm32_defconfig | 2 +- arch/microblaze/configs/mmu_defconfig | 2 +- arch/mips/configs/rs90_defconfig | 2 +- arch/powerpc/configs/adder875_defconfig | 2 +- arch/powerpc/configs/ep88xc_defconfig | 2 +- arch/powerpc/configs/mpc866_ads_defconfig | 2 +- arch/powerpc/configs/mpc885_ads_defconfig | 2 +- arch/powerpc/configs/tqm8xx_defconfig | 2 +- arch/riscv/configs/nommu_k210_defconfig | 2 +- arch/riscv/configs/nommu_k210_sdcard_defconfig | 2 +- arch/riscv/configs/nommu_virt_defconfig | 2 +- arch/sh/configs/edosk7705_defconfig | 2 +- arch/sh/configs/se7619_defconfig | 2 +- arch/sh/configs/se7712_defconfig | 2 +- arch/sh/configs/se7721_defconfig | 2 +- arch/sh/configs/shmin_defconfig | 2 +- init/Kconfig | 10 +++------- tools/testing/selftests/wireguard/qemu/kernel.config | 1 - 24 files changed, 25 insertions(+), 30 deletions(-) diff --git a/arch/arm/configs/collie_defconfig b/arch/arm/configs/collie_defconfig index 01b5a5a73f037..42cb1c8541188 100644 --- a/arch/arm/configs/collie_defconfig +++ b/arch/arm/configs/collie_defconfig @@ -3,7 +3,7 @@ CONFIG_LOG_BUF_SHIFT=14 CONFIG_BLK_DEV_INITRD=y #
