powerpc/kdump: Fix powernv build break when KEXEC_CORE=n
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 can get HMI's") Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Balbir Singh <bsingharora@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
