[PATCH] Fix for CONFIG_NUMA without CONFIG_SWAP

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.  However, calls to
migration functions will fail.
