This adds a function to dump the DMA mappings that the debugging code is
aware of -- either for a single device, or for _all_ devices.

This can be useful for debugging -- sticking a call to it in the DMA
page fault handler, for example, to see if the faulting address _should_
be mapped or not, and hence work out whether it's IOMMU bugs we're
seeing, or driver bugs.

I'd also like to make it answer the question 'should address X be mapped
for device Y', but I'll get to that next.

Do we have a %pX format for printing dma_addr_t yet?

Sample output below (2 of ~2500 faults), pages don't appear to be mapped:
(interesting hash_fn spread ;-)

Thanks. Your code to hook it up is better than mine too. I'll steal
that.

What machine did you get that on?

Yeah, I saw one of those. If could be a driver bug, of course -- it
could be unmapping a range before it's actually finished with it. But
that's unlikely.

An alternative explanation... The DMA is aborted¹, and the device
interrupts us to tell us about it at the _same_ time that the IOMMU
interrupts us to tell us about the fault. We process the device
interrupt first, unmap that buffer. And then we process the IOMMU
interrupt... and the buffer is already gone from the list.

It might be interesting to make this code also remember and print the
last range that was unmapped, as well as the currently-mapped ranges.

Yeah, that's a little suboptimal, isn't it :)

That's a T400 (I'd expect it's same issue as X200).

One thing I noticed is many of the faults are the page prior to a
coherent range 0x8000 in length, which seems to correspond to tfd buffer.
No obvious off-by-one error anywhere, and not all faults fit that pattern,
so w/out more iwlagn driver knowledge hard to say if that's meaningful
or just mapping coincidence.

I'd have expected the iommu fault to be delivered first, but hey...

That's what I was thinking too.  Almost need a flight recorder mode to
see if the range was ever mapped/unmapped.

Looks like driver is doing the right thing.

Hmm, thats because all device addresses are 16kb aligned. The hashfn
uses bits 13 to 21 as the index for the hash. I can move this window up
to bits 18-26 if it improves the hash spread.

Great. Thanks. Applied to my dma-api/debug branch.
