Michael Anderson 139a1d2842 powerpc/mm: Use UV_WRITE_PATE ucall to register a PATE ... When Ultravisor (UV) is enabled, the partition table is stored in secure memory and can only be accessed via the UV. The Hypervisor (HV) however maintains a copy of the partition table in normal memory to allow Nest MMU translations to occur (for normal VMs). The HV copy includes partition table entries (PATE)s for secure VMs which would currently be unused (Nest MMU translations cannot access secure memory) but they would be needed as we add functionality. This patch adds the UV_WRITE_PATE ucall which is used to update the PATE for a VM (both normal and secure) when Ultravisor is enabled.
