Hi,

These patches remove the last few modular apply_to_page_range() users and
unexports these interface. Since these functions provide direct access to our
page-tables they're a prime target for nefarious activities.

These patches rely on the remap_pfn_range_notrack() patches from Christoph that
are currently already in Andrew's tree.

Please consider.

This would be your robot not including the remap_pfn_range_notrack()
patches from Christoph I suppose..
