Build failure with 3.9.3 (Regression 3.9.2->3.9.3)

[Adam Lackorzynski]

Hi,

3.9.3 introduced the following build failure:

  CC      arch/powerpc/kernel/rtas.o
arch/powerpc/kernel/rtas.c: In function ‘rtas_cpu_state_change_mask’:
arch/powerpc/kernel/rtas.c:843:4: error: implicit declaration of function ‘cpu_down’ [-Werror=implicit-function-declaration]
cc1: all warnings being treated as errors
make[1]: *** [arch/powerpc/kernel/rtas.o] Error 1
make: *** [arch/powerpc/kernel] Error 2

My kernel config has CONFIG_HOTPLUG_CPU off, that's why cpu_down is not
defined. Shall CONFIG_HOTPLUG_CPU just be enabled or should the code in
rtas.c be adapted?


Thanks,
Adam
