Kirill A. Shutemov 6c7c3c21f9 x86: implement la57 paging mode
The new paging more is extension of IA32e mode with more additional page
table level.

It brings support of 57-bit vitrual address space (128PB) and 52-bit
physical address space (4PB).

The structure of new page table level is identical to pml4.

The feature is enumerated with CPUID.(EAX=07H, ECX=0):ECX[bit 16].

CR4.LA57[bit 12] need to be set when pageing enables to activate 5-level
paging mode.
