Subject: [PATCH 3/3] KVM: arm/arm64: Drop spurious message when faulting on a non-existent mapping
Date: Wed, 11 Dec 2019 16:56:50 +0000 [thread overview]
Message-ID: <20191211165651.7889-4-maz@kernel.org> (raw)
In-Reply-To: <20191211165651.7889-1-maz@kernel.org>
Should userspace unmap memory whilst the guest is running, we exit
with a -EFAULT, but also having spat a useless message on the console.
Get rid of it.
