Subject: [GIT PULL] (swiotlb) for 4.10

Hey Linus,

Please git pull the following branch:

 git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb.git stable/for-linus-4.10

It has one fix to make i915 work when using Xen SWIOTLB,
and a feature from Geert to aid in debugging of devices
that can't do DMA outside the 32-bit address space.

The feature from Geert is on top of v4.10 merge window commit
(specifically you pulling my previous branch), as his changes were
dependent on the Documentation/ movement patches.

I figured it would just easier than me trying than to
cherry-pick the Documentation patches to satisfy git.

The patches have been soaking since 12/20, albeit I updated
the last patch due to linux-next catching an compiler error
and adding an Tested-and-Reported-by tag.

Thanks!
