We are going to reduce reserved memory consumption by page table buffer, then OS can have more available memory to use. Take PhysicalAddressBits = 48 and 2MB page granularity as example, 1:1 Virtual to Physical identity mapping page table buffer needs to be ((512 + 1) * 512 + 1) * 4096 = 1075843072 bytes = 0x40201000 bytes. The code is updated to build 4G page table by default and only use 8 extra pages to handles > 4G request by page fault.
