Some ACPI static tables, such as SRAT, DMAR, PMTT and NFIT, also contain proximity IDs. This patch exports acpi_map_pxm_to_node() so that ACPI kernel modules can call this function to map a proximity ID to a node ID from an ACPI static table as well. When CONFIG_ACPI_NUMA is not set, acpi_map_pxm_to_node() always returns 0.
