mmap() & mmap_region() methods are removed from ACPI & DMI components, and we replace them with the new MM.allocate_kernel_region() helper. Instead of doing a raw calculation for each VM address, from now on we can use helper functions to do perform those calculations in a neat, reusable and readable way.
