    nvmm - Change NVMM_MAX_RAM
    * Add __NetBSD__ conditional back in with original 128GB limit.
    * Set DragonFly limit to 127TB (down from 128TB) to ensure that
      no valid memory exists at the canonical transition.
      Additional limits may have to be set as Intel specifies that the
      backing memory map not have an address space larger than the
      hardware's physical address space.
