ACPI: HMAT: ACPI_HMAT_MEMORY_PD_VALID is deprecated since ACPI-6.3 (35b9ad84) · Commits · 戴 / test

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:
