[PATCH 0/7] ksm: responses to NUMA review

[Hugh Dickins]

Here's a second KSM series, based on mmotm 2013-02-19-17-20: partly in
response to Mel's review feedback, partly fixes to issues that I found
myself in doing more review and testing.  None of the issues fixed are
truly show-stoppers, though I would prefer them fixed sooner than later.

1 ksm: add some comments
2 ksm: treat unstable nid like in stable tree
3 ksm: shrink 32-bit rmap_item back to 32 bytes
4 mm,ksm: FOLL_MIGRATION do migration_entry_wait
5 mm,ksm: swapoff might need to copy
6 mm: cleanup "swapcache" in do_swap_page
7 ksm: allocate roots when needed
