From 41d7a6d637e1440f5410cb43c25a3c41255540c5 Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Fri, 19 Jun 2015 12:18:33 -0600 Subject: libnvdimm: Set numa_node to NVDIMM devices ACPI NFIT table has System Physical Address Range Structure entries that describe a proximity ID of each range when ACPI_NFIT_PROXIMITY_VALID is set in the flags. Change acpi_nfit_register_region() to map a proximity ID to its node ID, and set it to a new numa_node field of nd_region_desc, which is then conveyed to the nd_region device. The device core arranges for btt and namespace devices to inherit their node from their parent region.
