This patch is based on Mel Gorman's old patch in the mailing list,
https://lkml.org/lkml/2015/5/5/280 which is dicussed but it is
fixed with a completion to wait for all memory initialised in
page_alloc_init_late(). It is to fix the oom problem on X86
with 24TB memory which allocates memory in late initialisation.
But for Power platform with 32TB memory, it causes a call trace
in vfs_caches_init->inode_init() and inode hash table needs more
memory.
So this patch allocates 1GB for 0.25TB/node for large system
as it is mentioned in https://lkml.org/lkml/2015/5/1/627
