But at this point I just want to have a # working system so that I can continue the merge window work tomorrow. # # Cc: Takashi Iwai <tiwai@suse.de> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 4b820e167bf6f410ace479d8df5b15a574000e75 # < make -s -j 48 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- allnoconfig # < make -s -j 48 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- help # make -s -j 48 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 48 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/linus_s390-allnoconfig_s390x-gcc4.9 # Build took: 0:00:23.845583
