Unmap pages from the kernel linear mapping after free_pages().

help
Fill the pages with poison patterns after free_pages() and verify
the patterns before alloc_pages(). This results in a large slowdown,
but helps to find certain types of memory corruptions.
This option cannot enalbe with hibernation. Otherwise, it will get
wrong messages for memory corruption because the free pages are not
saved to the suspend image.
