Konstantin Khlebnikov c2e7e00b71 mm/memory-failure: fix race with compound page split/merge 
get_hwpoison_page() must recheck relation between head and tail pages.

n-horiguchi said: without this recheck, the race causes kernel to pin an
irrelevant page, and finally makes kernel crash for refcount mismatch.
