Subject: [PATCH v3 15/15] arm64: kvm: Lift instrumentation restrictions on VHE
Date: Thu, 18 Jun 2020 13:25:37 +0100 [thread overview]
Message-ID: <20200618122537.9625-16-dbrazdil@google.com> (raw)
In-Reply-To: <20200618122537.9625-1-dbrazdil@google.com>
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.
