swiotlb on arm status

[Stefano Stabellini]

Hi Russell,
I thought about giving you a quick summary of the status of the swiotlb
patch series on ARM: it has been in linux-next since last week, a few
issues were found and fixed already.

I went through all the patches and I am still missing few acks on the
arm specific bits:

http://marc.info/?l=linux-kernel&m=138359037113882&w=2
The latest version of the "make SWIOTLB available" patch, on which you
have already commented in the past. This version should address your
previous feedback.

http://marc.info/?l=linux-kernel&m=138269913107769&w=2
This one is about not merging bio_vecs on Xen. The idea and the code is
taken from x86. The arm64 part has been acked by Catalin, but the arm32
part is still missing an ack. It introduces a build issue on
ape6evm_defconfig, fixed separately by the patch below. 

http://marc.info/?l=linux-kernel&m=138374169030300&w=2
A fix for the build issue found by Olof on linux-next on
ape6evm_defconfig.

Cheers,

Stefano

Russell,
sorry to harass you again, but I am starting to be worried about missing
the merge window. Could you please take a last look at these patches?

Well, as far as this patch goes, yes it's fine.

Acked-by: Russell King <rmk+kernel@arm.linux.org.uk>

But I wonder what's happening with xgmac?  Will it get fixed?

Rob sent a patch to fix it. I tested it and it works.
