1.1 Hierarchical 4-level per address space page tables |
SPARTAN kernel deploys generic interface for 4-level page tables |
for these architectures: amd64, ia32, mips32 and ppc32. In this |
setting, page tables are hierarchical and are not shared by |
address spaces (i.e. one set of page tables per address space). |
