It's not used by qemu, I guess there is/was a Freescale hypervisor that

Yes, there is/was a Freescale hypervisor that I and a few others worked
on. I've added a couple people on CC that might be able to tell the
current disposition of it.
But maybe it's time to remove it if it's not being maintained/used by
anyone?
I wouldn't be completely opposed to that if there really are no more
users. There really weren't any users even when I wrote the driver.
I haven't had a chance to study the patch, but my first instinct is that
there's got to be a better way to fix this than introducing a memcpy.
