ARM: pgtable: move TOP_PTE address definitions to arch/arm/mm/mm.h
Move the TOP_PTE address definitions to one central place so that it's easy to discover what they're being used for. This helps to ensure that there are no overlaps. Reviewed-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
