Patch 0.22pre2 for 2.4.17

This version features the adaptable vswap implementation. It's the first version and have to be improved, but it seems stable though. One of the improvements is to deal with many shrink and grows in a row (what I think it's stable but not completely functional). And we still have to deal with a possible find_vma failure, what will cause a BUG() in the current code.
