[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. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
