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.
EAL: Detected 8 lcore(s)
EAL:   cannot open VFIO container, error 2 (No such file or directory)
EAL: VFIO support could not be initialized
EAL: Setting up memory...

1: [./build/l2fwd(rte_dump_stack+0x18) [0x471828]]
--------------------------------------------

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


Thanks,
Tetsuya
