The types are # compatible, and there's no warning - but the result is just random # garbage. # # No, I don't think we've ever hit that issue in practice, but since we # now have sane infrastructure for doing this right, let's just use it. # It fixes any excessive expansion, and also avoids these kinds of broken # type issues. # # Requested-by: David Laight <David.Laight@aculab.com> # Acked-by: Arnd Bergmann <arnd@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 21b136cc63d2a9ddd60d4699552b69c214b32964 # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- allnoconfig # < make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- Completed OK # rm -rf /kisskb/build/linus_allnoconfig_mipsel-gcc5 # Build took: 0:00:19.182818
