arm/arm64: KVM : Enable vhost device selection under KVM config menu
vhost drivers provide guest VMs with better I/O performance and lower CPU utilization. This patch allows users to select vhost devices under KVM configuration menu on ARM. This makes vhost support on arm/arm64 on a par with other architectures (e.g. x86, ppc). Signed-off-by: Wei Huang <wei@redhat.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
