This bug leads to getting incorrect vcpupin information via qemudDomainGetVcpuPinInfo() API when the number of maximum cpu on a host falls into a range such as 31 < ncpus < 64. gcc warning: left shift count >= width of type The following bug is such the case https://bugzilla.redhat.com/show_bug.cgi?id=876415
