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

This results in a large slowdown, but helps to find certain types

of memory corruptions.

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.
