The current VFIO-on-POWER implementation supports only user mode

However this approach is really slow, so we want to move that to KVM.
Since H_PUT_TCE can be extremely performance sensitive (especially with
network adapters where
The existing TCE machine calls (tce_build and tce_free) only support

This adds real mode handlers for the H_PUT_TCE_INDIRECT and
H_STUFF_TCE hypercalls for user space emulated devices such as IBMVIO
devices or emulated PCI. These calls allow adding multiple entries

It does not make much sense to have KVM in book3s-64bit and
not to have IOMMU bits for PCI pass through support as it costs little
and allows VFIO to function on book3s-kvm.
Having IOMMU_API always enabled makes it unnecessary to have a lot of
#ifdef IOMMU_API in arch/powerpc/kvm/book3s_64_vio*.
The TCE tables handling may differ for real and virtual modes so
additional ppc_md.tce_build_rm/ppc_md.tce_free_rm/ppc_md.tce_flush_rm
handlers were introduced earlier.
So this adds the following:

This adds special support for huge pages (16MB) in real mode.
