So let's remove it. Andy suggested that the changes of the PTEs can be
avoided (excluding the direct-mapping alias), which is true. However,
in x86 it requires some cleanup of the contiguous page allocator, which
is outside of the scope of this patch-set.

I think x86-cpa stands for change_page_attr() :-)

Thanks - it makes much more sense… I took the first thing that Google
showed.
