Changes from PULL v1: reverted a commit that was also in Andrew Morton's tree, to resolve a merge conflict: this is what Stephen Rothwell was doing to resolve it in linux-next. Now that many more architectures build vhost, a couple of these (um, and arm with deprecated oabi) have reported build failures with randconfig, however fixes for that need a bit more discussion/testing and will be merged separately. Not a regression - these previously simply didn't have vhost at all. Also, there's some DMA API code in the vdpa simulator is hacky - if no solution surfaces soon we can always disable it before release: it's not a big deal either way as it's just test code.
