Subject: [PATCH 15/15] arm64: kvm: Lift instrumentation restrictions on VHE
Date: Thu, 30 Apr 2020 15:48:31 +0100
Message-ID: <20200430144831.59194-16-dbrazdil@google.com> (raw)
In-Reply-To: <20200430144831.59194-1-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.
