Revert "vhost: access vq metadata through kernel virtual address"
vhost: re-introducing metadata acceleration through kernel virtual
address
There are a bunch of patches in the queue already that will help
vhost, and I a working on one for next cycle that will help alot more
too.
I will check those patches, but if you can give me some pointers or keywords
it would be much appreciated.
You can look here:
https://github.com/jgunthorpe/linux/commits/mmu_notifier
The first parts, the get/put are in the hmm tree, and the last part,
the interval tree in the last commit is still a WIP, but it would
remove alot of that code from vhost as well.

Thanks a lot, will have a look at these and come back if I met any issues.
