From f5fe0adeed6019df495497a64cb57d563ead2296 Mon Sep 17 00:00:00 2001 From: Wujie Duan Date: Mon, 18 Mar 2024 17:47:35 +0800 Subject: KVM: arm64: Fix out-of-IPA space translation fault handling Commit 11e5ea5242e3 ("KVM: arm64: Use helpers to classify exception types reported via ESR") tried to abstract the translation fault check when handling an out-of IPA space condition, but incorrectly replaced it with a permission fault check. Restore the previous translation fault check.
