Subject: [PATCH 4/4] usb: allocated usb releated dma buffer with kmalloc_node
[PATCH 4/4] usb: allocated usb releated dma buffer with kmalloc_node
For amd64 based two way system. USB always on node0. but dma buffer for urb
allocated via kmalloc always get ram on node1. So change to kmalloc_node to
get dma_buffer on corresponding node.
