Christophe Leroy e97c59c35e powerpc/mm: Fix boot warning with hugepages and CONFIG_DEBUG_VIRTUAL 
[ Upstream commit e7e846dc6c73fbc94ae8b4ec20d05627646416f2 ]

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.  Only allocated 0 hugepages.

This is due to virt_addr_valid() using high_memory before it is set.

high_memory is set in mem_init() using max_low_pfn, but max_low_pfn
is available long before, it is set in mem_topology_setup(). So just
like commit daa9ada2093e ("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.
