> There is no sync between host and guest to allow removal of memzones,
> and freeing them result in undefined behavior.
> In the guest, we identify IVSHMEM memsegs/memzones by having
> ioremap_addr != 0. In the host, nothing is done to the memzone, meaning
> ioremap_addr == 0.
> As a solution, mark memzones being added to IVSHMEM in the host, by
> setting ioremap_addr, then return an error whenever we try to free an
> IVSHMEM memzone.
> Fixes: ff909fe21f0 ("mem: introduce memzone freeing")
