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")
