[PATCH] USB: UHCI: Split apart the physical and logical framelist arrays

Browse source 
This patch (as563) splits the physical and logical framelist arrays in
uhci-hcd into two separate pieces.  This will allow slightly better memory
utilization, since each piece is no larger than a single page whereas
before the whole thing was a little bigger than two pages.  It also allows
the logical array to be allocated in non-DMA-coherent memory.
