arm64/mm: remove unnecessary boundary check
Remove the unnecessary boundary check since there is a huge gap between user and kernel address that they would never overlap. (arm64 does not have enough levels of page tables to cover 64-bit virtual address) See Documentation/arm64/memory.txt Signed-off-by: Miles Chen <miles.chen@mediatek.com> Acked-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
