FreeBSD/src 1223b40 (r355783) — sys/powerpc/powernv platform_powernv.c opal.h
powerpc/powernv: Set the PTCR for the Nest MMU The Nest MMU manages address translation for accelerators on the POWER9. To do so, it needs a page table, so export the system page table to the Nest MMU. This will quietly fail on pre-POWER9 systems that do not have a NMMU. The NMMU is currently unused, so this change is currently effectively a NOP, but the NMMU and VAS will eventually be used.
