> Add support for using hugepages for worker lcore stack memory.  The
> intent is to improve performance by reducing stack memory related TLB
> misses and also by using memory local to the NUMA node of each lcore.
> 
> EAL option '--huge-worker-stack [stack-size-kbytes]' is added to allow
> the feature to be enabled at runtime.  If the size is not specified,
> the system pthread stack size will be used.
