Like ZICBOM, the ZICBOZ extension requires passing extra information to

from the kvm ioctl and pass into the guest via the device-tree info.

Hi Ben,
I have a patch almost identical to this one here
https://github.com/jones-drew/kvmtool/commit/f44010451e023b204bb1ef9767de20e0f20aca1c
The differences are that I don't add the header changes in this patch
(as they'll come with a proper header update after Linux patches get
merged), and I forgot to add the disable-zicboz, which you have.
I was planning on posting after the Linux patches get merged so
I could do the proper header update first.
I thought they had been, I just cherry-picked them (although I may
have just used linux-next instead of linux-upstream). I've been testing
this under qemu so it seems to be working so far with what i've been
doing.
