[PATCH 3/3] s390/dma: Allow per device dma ops
...nfig HAS_DMA
def_bool PCI
select HAVE_DMA_API_DEBUG
Should we maybe select HAVE_DMA_API_DEBUG above, drop the HAS_DMA
config option and rely on not defining NO_DMA instead?
Otherwise, the patch looks good to me.

Hmm, yes. That would simplify things a lot. Right now we include
lib/Kconfig (which defines HAS_DMA) and define it ourselfes in
arch/s390/Kconfig. WHoever comes first wins. Adding a select statement
would make this even more complicated.
Andy, I will simply send you a respin of this pa...

[PATCHv3 0/3] dma ops and virtio
Andy,
this is the next and hopefully last version. Seems to work fine
when replacing the previous patches in your tree. I have some
reviews/acks for patch 2 and 3. patch 1 still needs one ack.
Can you replace the patches in your tree and carry them along
with your changes?
old introduction:

There are some attempts to unify the dma ops (Christoph) as well
as some attempts to make virtio use

Is there a way to map pv guest pseudo physical address into dom0?
Hi, all
I''m reading the code of QEMU''s virtio infrastructure (hw/virtio.c) and
Linux''s virtio driver (virtio_blk.c, virtio_net.c).
Virtio drivers utilize scatter gather infrastructure in the Linux
kernel. It stores the physical addresses in scatter list. In Xen''s hvm
case, QEMU can access guest address space with
cpu_physical_memory_map.
However, in
