From: Wentao Wang <wwentao@vmware.com>
[ Upstream commit cf71d59c2eceadfcde0fb52e237990a0909880d7 ]
vcpuHint has been expanded to 16 bit on host to enable routing to more CPUs. Guest side should align with the change. This change has been tested with hosts with 8-bit and 16-bit vcpuHint, on both platforms host side can get correct value.
