This does that by just # removing the CC_ prefix entirely for the user choices, because it really # is not about the compiler support (the compiler support now instead # automatially impacts _visibility_ of the options to users). # # This results in "make oldconfig" actually asking the user for their # choice, so that we don't have any silent subtle security model changes. # The end result would generally look like this: # # CONFIG_HAVE_CC_STACKPROTECTOR=y # CONFIG_CC_HAS_STACKPROTECTOR_NONE=y # CONFIG_STACKPROTECTOR=y # CONFIG_STACKPROTECTOR_STRONG=y # CONFIG_CC_HAS_SANE_STACKPROTECTOR=y # # where the "CC_" versions really are about internal compiler # infrastructure, not the user selections. # # Acked-by: Masahiro Yamada <yamada.masahiro@socionext.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 050e9baa9dc9fbd9ce2b27f0056990fc9e0a08a0 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_pseries_le_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- pseries_le_defconfig # Added to kconfig CONFIG_NUMA=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_pseries_le_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_pseries_le_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
