Hi Hans,
on kernel 2.6.32 (Ubuntu 10.04) the media_build tree compiles fine, with
just a few remaining warnings.

In particular, there are several new warnings related to DMA_SHARED_BUFFER:

WARNING: "dma_buf_vunmap" [media_build/v4l/videobuf2-vmalloc.ko] undefined!
WARNING: "dma_buf_vmap" [media_build/v4l/videobuf2-vmalloc.ko] undefined!
WARNING: "dma_buf_fd" [media_build/v4l/videobuf2-core.ko] undefined!
WARNING: "dma_buf_put" [media_build/v4l/videobuf2-core.ko] undefined!
WARNING: "dma_buf_get" [media_build/v4l/videobuf2-core.ko] undefined!
