/*
* This macro is taken from libvirt: https://gitlab.com/libvirt/libvirt/commit/bfc72e99920215c9b004a5380ca61fe6ff81ea6b
*
* libxl interface for setting VCPU affinity changed in 4.5. In fact, a new
* parameter has been added, representative of 'VCPU soft affinity'. If one
* does not care about it (and that's libvirt case), passing NULL is the
* right thing to do. To mark that change, LIBXL_HAVE_VCPUINFO_SOFT_AFFINITY
* is defined.
