Hi Naoya or Greg,
f15bdfa802bfa5eb6b4b5a241b97ec9fa1204a35
mm/memory-failure.c: fix memory leak in successful soft offlining
This patche look applicable to stable-3.10.
After a successful page migration by soft offlining, the source
page is not properly freed and it's never reusable even if we
unpoison it afterward. This is caused by the race between freeing
page and setting PG_hwpoison.
It was built successful for me. What do you think?
Thanks,
Xishi Qiu

I agree to sending this patch into the stable.
I should've added "cc: stable" tag in patch description.
Thanks,
