Hey Linus,

Please git pull the following branch in your tree:

git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb.git stable/for-linus-4.17

There is one single fix in there - that is under Xen the DMA32 heap
(in the hypervisor) would end up looking like swiss cheese. The reason
being that for every coherent DMA allocation we didn't do the proper
hypercall to tell Xen to return the page back to the DMA32 heap.
End result was (eventually) no DMA32 space if say you say continously
unloaded and loaded modules.

Thank you.
