Subject: powerpc: export cpu_to_core_id()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f8ab481066e7246e4b272233aa0b6948f5069f41;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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 <linux/topology.h> (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.
