But let's keep some code quality standards here, and not # accept outrageously bad code. # # Link: https://lore.kernel.org/lkml/CAHk-=wgV9toS7GU3KmNpj8hCS9SeF+A0voHS8F275_mgLhL4Lw@mail.gmail.com/ # Cc: Andy Lutomirski <luto@kernel.org> # Cc: Thomas Gleixner <tglx@linutronix.de> # Cc: Peter Zijlstra (Intel) <peterz@infradead.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux-ld --version # < git log --format=%s --max-count=1 bb5a93aaf25261321db0c499cde7da6ee9d8b164 # < make -s -j 8 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- defconfig # < make -s -j 8 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- help # make -s -j 8 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- olddefconfig # make -s -j 8 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: modpost: "saved_config" [vmlinux] is COMMON symbol Kernel arch/alpha/boot/vmlinux.gz is ready Completed OK # rm -rf /kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 # Build took: 0:01:13.495317
