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 [ 0.000000] initial memory mapped : 0 - 20000000 [ 0.000000] init_memory_mapping: [0x00000000000000-0x0000007f74ffff] [ 0.000000] 0000000000 - 007f600000 page 2M [ 0.000000] 007f600000 - 007f750000 page 4k [ 0.000000] kernel direct mapping tables up to 7f750000 @ [0x7f74c000-0x7f74ffff] [ 0.000000] RAMDISK: 7bc84000 - 7f745000 ....
