    Subject[PATCH 1/2] powerpc/kdump: Add missing optional dummy functions
    Date
    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.

    Fixes: 4145f358644b ("powernv/kdump: Fix cases where the kdump kernel ...")
