commit 7798ed0f57b4d137e660fbf5be1e1528e40f89ac

    generic-ipi: powerpc/generic-ipi tree build failure
    
    Today's linux-next build (powerpc allmodconfig) failed like this:
    
    ERROR: ".save_stack_trace" [tests/backtracetest.ko] undefined!
    
    But save_stack_trace is exported in arch/powerpc/kernel/stacktrace.c
    
    I couldn't figure it out until I noticed these earlier warnings:
    
    arch/powerpc/kernel/stacktrace.c:47: warning: data definition has no type or storage class
    arch/powerpc/kernel/stacktrace.c:47: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL'
    arch/powerpc/kernel/stacktrace.c:47: warning: parameter names (without types) in function declaration
    
    I applied the patch below.
