[PATCH] convert x86_64 to 4 level page tables
Converted to true 4levels. The address space per process is expanded to
47bits now, the supported physical address space is 46bits.
Lmbench fork/exit numbers are down a few percent because it has to walk
much more pagetables, but some planned future optimizations will
hopefully recover it.
See Documentation/x86_64/mm.txt for more details on the memory map.
