From 6c47506361ecd9591813bbaaca518f8a76162a3d Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Thu, 8 Feb 2018 09:58:52 +0000 Subject: [PATCH] ACPI/IORT: Remove temporary iort_get_id_mapping_index() ACPICA guard In IORT issue C SMMUv3 IORT nodes gained an additional field (DeviceID mapping index) so that the SMMUv3 can describe its MSI interrupts. Referring to it in the kernel requires ACPICA changes and in order to prevent kernel<->ACPICA dependencies kernel code depending on the SMMUv3 DeviceID mapping index field was guarded with an ACPICA version conditional. ACPICA changes introducing DeviceID mapping index in the IORT structs were integrated in the kernel with: commit 4c106aa411ee ("ACPICA: iasl: Add SMMUv3 device ID mapping index support") so the temporary ACPICA guard has become stale and can be removed.
