Subject: [PATCH 2/4] ACPICA: ACPI 6.4 SRAT: add Generic Port Affinity type

From: Alison Schofield <alison.schofield@...el.com>

ACPICA commit 777e11b73e60f0eb606cf20142ef634702b09ba1

Add a new subtable type for SRAT Generic Port Affinity.
It uses the same subtable structure as the existing Generic
Initiator Affinity type.
