Hi,

Commit b987812b3fc "powerpc/kexec: Fix mismatched ifdefs for PPC64/SMP."
breaks compilation on non SMP powerpc machines.
I wonder if this commit is really neccessary in the first place. The
function definition itself is already between an

#ifdef CONFIG_SMP (line 56)
#endif 

block so only exists if SMP=y and PPC_STD_MMU_64=y.
Furthermore the stub in your patch is only created if SMP=y and
PPC_STD_MMU_64=n which breaks non-SMP configs. 

Kind regards,
Michael Guntsche
