CONFIG_MIGRATION is not set, no CONFIG_MIGRATION entry is in .config, so page migration was not compiled in. You also forgot to do "make oldconfig" when building the kernel. If you do a "make oldconfig" then your kernel will be build with page migration support.
Either what we see is due to code rearrangement or there is something wrong with the fallback definitions in include/linux/swapops.h.
The swapless-pm-add-r-w-migration-entries.patch also introduces Hugh's reversal of the anon_vma list. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
