Hi Jianfeng and Xie,

I guess my implementation and yours have a lot of common code, so I will
try to rebase my patch on yours.

BTW, one thing I need to change your memory allocation way is that
mmaped address should be under 44bit(32 + PAGE_SHIFT) to work with my patch.
This is because VIRTIO_PCI_QUEUE_PFN register only accepts such address.
(I may need to add one more EAL parameter like "--mmap-under <address>")

I believe it is OK to mmap under 44bit, but better check the user space
address space layout.

Thanks,
Tetsuya
