Hi All, This 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 both native, HYP and stage2 sides. This series is validated with Fast Models and kvmtool as platform and guest launcher, respectively.
