arm64: Introduce VA_BITS and translation level options
This patch adds virtual address space size and a level of translation tables to kernel configuration. It facilicates introduction of different MMU options, such as 4KB + 4 levels, 16KB + 4 levels and 64KB + 3 levels, easily. The idea is based on the discussion with Catalin Marinas: http://www.spinics.net/linux/lists/arm-kernel/msg319552.html Signed-off-by: Jungseok Lee <jays.lee@samsung.com> Reviewed-by: Sungjinn Chung <sungjinn.chung@samsung.com> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Tested-by: Jungseok Lee <jungseoklee85@gmail.com>
