Hi Srikar, Thank you for the patch! Yet something to improve: [auto build test ERROR on powerpc/next] [also build test ERROR on next-20200317] [cannot apply to linus/master asm-generic/master mpe/next v5.6-rc6] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Srikar-Dronamraju/Fix-kmalloc_no... base: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next config: powerpc-defconfig (attached as .config) compiler: powerpc64-linux-gcc (GCC) 9.2.0 reproduce: wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # save the attached .config to linux build tree GCC_VERSION=9.2.0 make.cross ARCH=powerpc If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp(a)intel.com&gt; All error/warnings (new ones prefixed by >>): In file included from include/linux/topology.h:36, from include/linux/gfp.h:9, from include/linux/slab.h:15, from include/linux/crypto.h:19, from include/crypto/hash.h:11, from include/linux/uio.h:10, from include/linux/socket.h:8, from include/linux/compat.h:15, from arch/powerpc/kernel/asm-offsets.c:14: arch/powerpc/include/asm/topology.h: In function 'update_default_numa_mem': 77 | reset_numa_mem(node); | ^~~~~~~~~~~~~~ arch/powerpc/include/asm/topology.h:79:1: warning: no return statement in function returning non-void [-Wreturn-type] 79 | } | ^ In file included from include/linux/gfp.h:9, from include/linux/slab.h:15, from include/linux/crypto.h:19, from include/crypto/hash.h:11, from include/linux/uio.h:10, from include/linux/socket.h:8, from include/linux/compat.h:15, from arch/powerpc/kernel/asm-offsets.c:14: include/linux/topology.h: At top level: 151 | static inline void reset_numa_mem(int node) | ^~~~~~~~~~~~~~ In file included from include/linux/topology.h:36, from include/linux/gfp.h:9, from include/linux/slab.h:15, from include/linux/crypto.h:19, from include/crypto/hash.h:11, from include/linux/uio.h:10, from include/linux/socket.h:8, from include/linux/compat.h:15, from arch/powerpc/kernel/asm-offsets.c:14: arch/powerpc/include/asm/topology.h:77:4: note: previous implicit declaration of 'reset_numa_mem' was here 77 | reset_numa_mem(node); | ^~~~~~~~~~~~~~ cc1: some warnings being treated as errors make[2]: *** [scripts/Makefile.build:101: arch/powerpc/kernel/asm-offsets.s] Error 1 make[2]: Target '__build' not remade because of errors. make[1]: *** [Makefile:1112: prepare0] Error 2 make[1]: Target 'prepare' not remade because of errors. make: *** [Makefile:179: sub-make] Error 2 256 real 58 user 115 sys 67.93% cpu make prepare vim +/reset_numa_mem +77 arch/powerpc/include/asm/topology.h 65 66 static inline int update_default_numa_mem(void) 67 { 68 unsigned int node; 69 70 for_each_node(node) { 71 /* 72 * For all possible but not yet online nodes, ensure their 73 * node_numa_mem is set correctly so that kmalloc_node works 74 * for such nodes. 75 */ 76 if (!node_online(node)) 78 } 79 } 80 #else 81 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org
