Subject: [PATCH RFT] sparc: dma-mapping: support debug_dma_mapping_error
Add support for debug_dma_mapping_error() call to avoid warning from
debug_dma_unmap() interface when it checks for mapping error checked
status. Without this patch, device driver failed to check map error
warning is generated.

Why are you resending this?
When you resend patches, you have to give a reason. Did the patch
change? Are you updating the CC: list of the patch posting? Are
you correcting something else?

In fact you sent this _3_ times. Please, don't do this, or at least
explain why you are reposting something each time.

I am really sorry for the noise. I forgot to mark this explicitly for
linux-next the first time and this patch depends on a patch that went
into linux-next. I sent a few patches for several architectures and lost
track. I meant to add explanation before I hit send. The reason for
resend is to tag it for linux-next.

The problem the dependent patch is in linux-next and not in arch trees
yet. That is why I am trying it get this through linux-next and/or
dma-debug tree. I am open to suggestions on what is the best route.
linux-next commit-id is:
commit 6c9c6d6301287e369a754d628230fa6e50cdb74b
I have another one that I sent to linux-next that fixes the dependency
on get_dma_ops():

Then please put this in via the dma-debug tree:

Marek,
This is for sparc to go through your tree.

Applied to dma-debug, thanks.
Btw, what about the patches for the other archs? They should depend on
the dma-debug branch too and should also be there, no?
