This patch appears to undo some of the changes made by patch 01/11.

Would it be an idea to merge them into one, so the first patch
introduces the right conventions directly?

The only reason this isn't merged into one, is that this requires
non obvious (not difficult though) to the core VM code. I wanted to
keep an obviously safe approach for 2.6.26. The other conventions are
only needed by XPMEM and XPMEM can't work without all other patches anyway.
