Subject: [PATCH v1 0/2] vpopcntdq support

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.

Regards,
Piotr
