I hit a large number of rejects applying this against linux-next. Due
to the increasingly irritating sched/numa code in there.
I attempted to fix it up and also converted some (but not all) of the
implicit tests of `rc' against zero.
Please check the result very carefully - more changes will be needed.
All those
- if (rc)
+ if (rc != MIGRATEPAGE_SUCCESS)
changes are a pain. Perhaps we shouldn't bother.
