The kernel page table creation routines are accessible to other subsystems (e.g., EFI) via the create_pgd_mapping() entry point, which allows mappings to be created that are not covered by init_mm. Since generic code such as apply_to_page_range() may expect translation table pages that are not associated with init_mm to be covered by fully constructed struct pages, add a call to pgtable_page_ctor() in the alloc function used by create_pgd_mapping. Since it is no longer used by create_mapping_late(), also update the name of this function to better reflect its purpose.
