[PATCH] USB: UHCI: Split apart the physical and logical framelist arrays
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. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
