[PATCH] [RFC] EHCI: add to memory barrier to updating hw_next

Hi, I have a missing urb completion problem on ARMv7 based platform. I thought the above problem was caused by coherent memory between the EHCI device and CPU so I tryied to allocates device type memory for EHCI via dma_declare_coherent_memory at machine initialization step so that EHCI always
