[dpdk-dev] rte_eal_init() causes PANIC using latest DPDK code.

[Tetsuya Mukawa <mukawa@igel.co.jp>]

Hi,

I've got following error using latest DPDK code.
Does someone face the same issue?
In my environment, It seems almost all DPDK apps (at lease l2fwd and
testpmd) cannot work.

EAL: Support maximum 128 logical core(s) by configuration.

I tried bisect, and it seems below patch causes this.
"eal: fix check for power of 2 in 0 case".


Thanks,
