From a4b6e1be2c8fd60381feb00f06cf3b6373bbbf07 Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Tue, 9 Mar 2021 11:27:39 +0100 Subject: [PATCH] hw/arm/smmu-common: Fix smmu_iotlb_inv_iova when asid is not set If the asid is not set, do not attempt to locate the key directly as all inserted keys have a valid asid. Use g_hash_table_foreach_remove instead.
