Use the new non-coherent DMA API including proper ownership transfers. This also means we can allocate the buffer memory with the proper direction instead of bidirectional.

Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported. I'm still a

I tried to start a domain that I knew would fail, as the vbd it would use was already in use. However, Xend entered a state that made xm unusable and I had to restart it: # xm create -c hal2.xm Using config file "./hal2.xm". /usr/lib/xen/bin/xenconsole: invalid option -- 1 Invalid number of arguments Try `/usr/lib/xen/bin/xenconsole --help'' for more information. # xm list Internal error: Device 769 (vbd) could not be connected.
