[PATCH v16 0/7] Parse ACPI table and limit KASLR to choosing immovable memory

***Background: People reported that KASLR may randomly choose some positions which are located in movable memory regions. This will make the movable memory chosen by KASLR can't be removed. ***Solutions: Get the information of memory hot-remove, then KASLR knows the right regions. Information
