Revert "powerpc: Set max_mapnr correctly"
This reverts commit 602946ec2f90d5bd965857753880db29d2d9a1e9. If CONFIG_HIGHMEM is enabled, no highmem will be added with max_mapnr set to max_low_pfn, see mem_init(): for (pfn = highmem_mapnr; pfn < max_mapnr; ++pfn) { ... free_highmem_page(); } Now that virt_addr_valid() has been fixed in the previous commit, we can revert the change to max_mapnr.
