This patch breaks a good half of my test configs with: /home/benh/linux-powerpc-test/arch/powerpc/kernel/sysfs.c: In function 'topology_init': /home/benh/linux-powerpc-test/arch/powerpc/kernel/sysfs.c:979:2: error: implicit declaration of function 'cpu_notifier_register_begin' [-Werror=implicit-function-declaration] /home/benh/linux-powerpc-test/arch/powerpc/kernel/sysfs.c:1004:2: error: implicit declaration of function '__register_cpu_notifier' [-Werror=implicit-function-declaration] /home/benh/linux-powerpc-test/arch/powerpc/kernel/sysfs.c:1006:2: error: implicit declaration of function 'cpu_notifier_register_done' [-Werror=implicit-function-declaration] cc1: all warnings being treated as errors make[2]: *** [arch/powerpc/kernel/sysfs.o] Error 1 make[2]: *** Waiting for unfinished jobs.... _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
