This a selection of patches on top of 2.6.17-rc4-mm1 that may
address additional requirements such as

- Automatic page migration from user space.
- Support for migration memory that has no page_structs.
- Move pages to the correct pages in memory areas with
  MPOL_INTERLEAVE policy.

Plus it does a significant cleanup of the code. All of these
patches will require additional feedback before they can get in.
If any of this code gets in then probably later than 2.6.18.

A test program for page based migration may be found with the patches
on ftp.kernel.org:/pub/linux/kernel/christoph/pmig/patches-2.6.17-rc4-mm1
