[dpdk-dev] [PATCH v3 4/4] examples/power: increase max cores to 256

[David Hunt <david.hunt@intel.com>]

Increase the number of addressable cores from 64 to 256. Also remove the
warning that incresing this number beyond 64 will cause problems (because
of the previous use of uint64_t masks). Now this number can be increased
significantly without causing problems.
