A processor supports AVX_VNNI instructions if CPUID.(EAX=7,ECX=1):EAX[bit 4]
is present.

This series includes kernel and kvm patches, kernel patch define this
new cpu feature bit and kvm expose this bit to guest. When this bit is
enabled on cpu or vcpu, the cpu feature flag is shown as "avx_vnni" in
/proc/cpuinfo of host and guest.

Detailed information on the instruction and CPUID feature flag can be
found in the latest "extensions" manual [1].
