This series contains a patch to clean up the HWPoisonHandlable and another one to dissolve truncated hugetlb page. More details can be found in the respective changelogs. This patch (of 2): The local variable movable can be removed by returning true directly. Also fix typo 'mirgate'. No functional change intended.
