Subject: [PATCH] RFC: cpu-topology: declare parse_acpi_topology in <linux/arch_topology.h>

The parse_acpi_topology() is not declared anywhere which
causes the following sparse warning:

drivers/base/arch_topology.c:522:19: warning: symbol 'parse_acpi_topology' was not declared. Should it be static?

RFC: is this the best place to put it?
