Hi, This patchset adds the support for new CPUID feature bit that announces the vector population count instructions for dwords and qwords.
The path 1/2 adds new feature flags and handles clearing the feature bit in case xsave is not enabled. The patch 2/2 enables passing the feature bit to a kvm/quemu guest. The patchset is based on v4.10-rc3.
