From 35b9ad840892d979dbeffe702dae95a3cbefa07b Mon Sep 17 00:00:00 2001 From: Daniel Black Date: Tue, 6 Aug 2019 14:24:39 +1000 Subject: ACPI: HMAT: ACPI_HMAT_MEMORY_PD_VALID is deprecated since ACPI-6.3 ACPI-6.3 corresponds to when HMAT revision was bumped from 1 to 2. In this version ACPI_HMAT_MEMORY_PD_VALID was deprecated and made reserved. As such in revision 2+ we shouldn't be testing this flag. This is as per ACPI-6.3, 5.2.27.3, Table 5-145 "Memory Proximity Domain Attributes Structure" for Flags. Signed-off-by: Daniel Black Reviewed-by: Tao Xu Signed-off-by: Rafael J.
