Say Y here if you want to show the stage-2 kernel pagetables
|
|
layout in a debugfs file. This information is only useful for kernel developers
|
|
who are working in architecture specific areas of the kernel.
|
|
It is probably not a good idea to enable this feature in a production

|
kernel.

If in doubt, say N.
