Hello!
I am now finishing v9 and (i hope) i fixed everything except this one. Sorry,
too many mails, i occasionally skipped this one earlier.

Yes, there is a reason. It is because of how in-kernel vITS works. It handles
only control region. Translation register has to be handled in userspace and
writes there need to be converted to KVM_SIGNAL_MSI ioctl. Therefore two
regions are more convenient to use.
