Description of changes:

[4.1.2-18.el5.51]
- libxc: limit cpu values when setting vcpu affinity
   When support for pinning more than 64 cpus was added, check for cpu
   out-of-range values was removed. This can lead to subsequent
   out-of-bounds cpumap array accesses in case the cpu number is higher
   than the actual count.
   This patch returns the check.
   This is CVE-2013-2072 / XSA-56
