From f9a026e3d38ba81cd274725f1caaf64322a86aa5 Mon Sep 17 00:00:00 2001 From: David Brazdil Date: Thu, 25 Jun 2020 14:14:20 +0100 Subject: [PATCH] KVM: arm64: Lift instrumentation restrictions on VHE With VHE and nVHE executable code completely separated, remove build config that disabled GCOV/KASAN/UBSAN/KCOV instrumentation for VHE as these now execute under the same memory mappings as the rest of the kernel. No violations are currently being reported by either KASAN or UBSAN.
