Date: Mon, 10 Aug 2020 10:59:42 -0500 From: Daniel Díaz <daniel.diaz@...aro.org> To: Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, Borislav Petkov <bp@...en8.de>, x86@...nel.org (maintainer:X86 ARCHITECTURE (32-BIT AND 64-BIT)), "H.

Currently, $ make i386_defconfig $ grep CONFIG_64BIT .config CONFIG_64BIT=y whereas previously (and with this patch now): $ make i386_defconfig $ grep CONFIG_64BIT .config # CONFIG_64BIT is not set This was found with weird compiler errors on OpenEmbedded builds, as the compiler was unable to cope with 64-bits data types: NOTE: make -j1 bzImage CC=i686-linaro-linux-gcc -fuse-ld=bfd -fdebug-prefix-map=/oe/build/tmp/work/intel_core2_32-linaro-linux/linux-generic-mainline/5.8+gitAUTOINC+1d0e12fd3a-r0=/usr/src/debug/linux-generic-mainline/5.8+gitAUTOINC+1d0e12fd3a-r0 -fdebug-prefix-map=/oe/build/tmp/work/intel_core2_32-linaro-linux/linux-generic-mainline/5.8+gitAUTOINC+1d0e12fd3a-r0/recipe-sysroot= -fdebug-prefix-map=/oe/build/tmp/work/intel_core2_32-linaro-linux/linux-generic-mainline/5.8+gitAUTOINC+1d0e12fd3a-r0/recipe-sysroot-native= -fdebug-prefix-map=/oe/build/tmp/work-shared/intel-core2-32/kernel-source=/usr/src/kernel -ffile-prefix-map=/oe/build/tmp/work/intel_core2_32-linaro-linux/linux-generic-mainline/5.8+gitAUTOINC+1d0e12fd3a-r0/git=/kernel-source/ LD=i686-linaro-linux-ld.bfd GEN Makefile CC scripts/mod/empty.o cc1: error: code model 'kernel' not supported in the 32 bit mode cc1: sorry, unimplemented: 64-bit mode not compiled in /oe/build/tmp/work-shared/intel-core2-32/kernel-source/scripts/Makefile.build:280: recipe for target 'scripts/mod/empty.o' failed make[2]: *** [scripts/mod/empty.o] Error 1 /oe/build/tmp/work-shared/intel-core2-32/kernel-source/Makefile:1174: recipe for target 'prepare0' failed make[1]: *** [prepare0] Error 2 /oe/build/tmp/work-shared/intel-core2-32/kernel-source/Makefile:185: recipe for target '__sub-make' failed make: *** [__sub-make] Error 2 Fixes: 1d0e12fd3a84 ("x86/defconfigs: Refresh defconfig files") Signed-off-by: Daniel Díaz <daniel.diaz@...aro.org> --- arch/x86/configs/i386_defconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/x86/configs/i386_defconfig b/arch/x86/configs/i386_defconfig index d7577fece9eb..4cfdf5755ab5 100644 --- a/arch/x86/configs/i386_defconfig +++ b/arch/x86/configs/i386_defconfig @@ -19,6 +19,7 @@ CONFIG_CGROUP_CPUACCT=y CONFIG_BLK_DEV_INITRD=y # CONFIG_COMPAT_BRK is not set CONFIG_PROFILING=y +# CONFIG_64BIT is not set CONFIG_SMP=y CONFIG_X86_GENERIC=y CONFIG_HPET_TIMER=y -- 2.25.1
