mm, hwpoison: use ClearPageHWPoison() in memory_failure()
Patch series "A few cleanup patches for memory-failure".
his series contains a few cleanup patches to use __PageMovable() to detect
non-lru movable pages, use num_poisoned_pages_sub() to reduce multiple
atomic ops overheads and so on. More details can be found in the
respective changelogs.
This patch (of 6):
Use ClearPageHWPoison() instead of TestClearPageHWPoison() to clear page
hwpoison flags to avoid unneeded full memory barrier overhead.
