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

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

of memory corruption.

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 corruption.

This option cannot be enabled in combination with hibernation as
|
|
that would result in incorrect warnings of memory corruption after
|
|
a resume because free pages are not saved to the suspend image.
