From f8ab481066e7246e4b272233aa0b6948f5069f41 Mon Sep 17 00:00:00 2001 From: Mauricio Faria de Oliveira Date: Thu, 2 Jun 2016 08:45:14 -0300 Subject: [PATCH] powerpc: export cpu_to_core_id() Export cpu_to_core_id(). This will be used by the lpfc driver. This enables topology_core_id() from (defined to cpu_to_core_id() in arch/powerpc/include/asm/topology.h) to be used by (non-builtin) modules. That is arch-neutral, already used by eg, drivers/base/topology.c, but it is builtin (obj-y in Makefile) thus didn't need the export. Since the module uses topology_core_id() and this is defined to cpu_to_core_id(), it needs the export, otherwise: ERROR: "cpu_to_core_id" [drivers/scsi/lpfc/lpfc.ko] undefined! Tested on next-20160601.
