Subject: [PATCH for-6.2 2/8] monitor: Use accel_find("kvm") instead of kvm_available()
Date: Fri, 30 Jul 2021 11:59:41 +0100	[thread overview]
Message-ID: <20210730105947.28215-3-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210730105947.28215-1-peter.maydell@linaro.org>

The kvm_available() function reports whether KVM support was
compiled into the QEMU binary; it returns the value of the
CONFIG_KVM define.

The only place in the codebase where we use this function is
in qmp_query_kvm(). Now that accelerators are based on QOM
classes we can instead use accel_find("kvm") and remove the
kvm_available() function.
