Just note, EXYNOS4 SoCs and EXYNOS5250 cannot boot when LPAE is enabled so I
think, single zImage should be handled separately for non-LPAE and LPAE. I
need to sort out EXYNOS SoCs for it and prepare registering
exynos5440_defconfig. Of course, EXYNOS5440 can be supported without LPAE
enabling but current bootargs in v3.11-rc1 break the kernel booting.
