#     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.
#     
#     Fixes: 602946ec2f90 ("powerpc: Set max_mapnr correctly")
