Hi All,

This the 2nd patchset supports 4 levels of tranlsation tables for ARM64.

Firstly, The patchset decouples page size from level of translation tables
as taking account into the comment from Catalin Marinas:
http://www.spinics.net/linux/lists/arm-kernel/msg319552.html

Then, it implements 4 levels of translation tables for native, HYP
and stage2 sides.

All ARMv8 and ARMv7 related changes are validated with FastModels+kvmtool
and A15+QEMU, respectively.

Changes since v1:
- fixed unmatched data types as per Steve's comment
- removed unnecessary #ifdef in arch/arm64/mm/* as per Steve's comment
- revised create_pgd_entry to deal with PUD entry as per Steve's comment
- introduced a macro for initial memblock limit as per Steve's comment
- dropped "Fix line length exceeding 80 characters" patch as per Marc's comment
- removed unnecessary #ifdef in arch/arm/kvm/mmu.c as per Marc's comment
- added a macro for a number of objects of as per Marc's comment

      arm64: Add 4 levels of page tables definition with 4KB pages
      arm64: mm: Implement 4 levels of translation tables
      arm64: KVM: Implement 4 levels of translation tables for HYP and stage2
