This change moves enabling these interrupts # earlier covering the function get_user(). While at this, lets check # for kernel mode and crash as this interrupt should not have been # triggered from the kernel context. # # Signed-off-by: Anshuman Khandual # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 95edc4da89c32317b6ce22c90cb4793d3646565d # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- powernv_defconfig # Added to kconfig CONFIG_NUMA=n # yes \n | make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_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 120 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- WARNING: modpost: Found 2 section mismatch(es).
