SubjectRe: 2.6.15-git9 build failure when CONFIG_SWAP is not set

-- Patch that was sent to Andrew.

Some people apparently run CONFIG_NUMA without CONFIG_SWAP. The migration
code currently depends on swap. This patch provides a set of inline fallback
functions so that the kernel properly compiles. Howeverver, calls to migration
functions will fail.
