[PATCH] videobuf-dma-contig: zero copy USERPTR support V2

2009-04-28 Thread Magnus Damm
From: Magnus Damm d...@igel.co.jp This is V2 of the V4L2 videobuf-dma-contig USERPTR zero copy patch. Since videobuf-dma-contig is designed to handle physically contiguous memory, this patch modifies the videobuf-dma-contig code to only accept a pointer to physically contiguous memory. For now
