Yinghai Lu 1411e0ec31 x86-64, numa: Put pgtable to local node memory 
Introduce init_memory_mapping_high(), and use it with 64bit.

It will go with every memory segment above 4g to create page table to the
memory range itself.

before this patch all page tables was on one node.

with this patch, one RED-PEN is killed

debug out for 8 sockets system after patch
