If KEXEC_CORE is not enabled, PowerNV builds fail as follows.
arch/powerpc/platforms/powernv/smp.c: In function 'pnv_smp_cpu_kill_self': arch/powerpc/platforms/powernv/smp.c:236:4: error: implicit declaration of function 'crash_ipi_callback'
Add dummy function calls, similar to kdump_in_progress(), to solve the problem.
