From 910961754572a2f4c83ad7e610d180e3e6c29bda Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 12 Feb 2018 14:34:07 -0800 Subject: 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.
