[dpdk-dev] examples/vm_power: fix improper physical core mask
Commit Message
From: Marvin Liu <yong.liu@intel.com>
Host cpu mapping structure can only support 64 cpus. When run vm_power sample
on platform with more than 64 cpus, will generate improper physical core mask.
After limited supported host cpus to 64 will fix this issue.
