[dpdk-dev] [PATCH] examples/vm_power: fix improper physical core mask

[Yong Liu]

From: Marvin Liu <yong....@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.
