Christophe Leroy e7e846dc6c powerpc/mm: Fix boot warning with hugepages and CONFIG_DEBUG_VIRTUAL ... Booting with CONFIG_DEBUG_VIRTUAL leads to following warning when passing hugepage reservation on command line: Kernel command line: hugepagesz=1g hugepages=1 hugepagesz=64m hugepages=1 hugepagesz=256m hugepages=1 noreboot HugeTLB: allocating 1 of page size 1.00 GiB failed.

So just like commit daa9ada209 ("powerpc/mm: Fix boot crash with FLATMEM") moved the setting of max_mapnr immediately after the call to mem_topology_setup(), the same can be done for high_memory.
