To # make it accurate, the pipe mutex would need to be taken or the spin # lock could be used - but usage of the spinlock would need to be # rolled out into splice, iov_iter and other places for that. # # - The index mask and the max_usage values cannot be cached across # pipe_wait() as F_SETPIPE_SZ could have been called during the wait. # This can cause pipe_write() to break" # # * pipe-rework: # pipe: Fix missing mask update after pipe_wait() # pipe: Remove assertion from pipe_poll() # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 da73fcd8cfdc3d0ef49280fa0d511723a0220e03 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # Added to kconfig CONFIG_NUMA=n # yes \n | make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: vmlinux.o(.text+0x2fc8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel() The function start_here_common() references the function __init start_kernel().
