Mizuma, Masayoshi e4e351a30a mm/hugetlb.c: add cond_resched_lock() in return_unused_surplus_pages() ... commit 7848a4bf51b34f41fcc9bd77e837126d99ae84e3 upstream. soft lockup in freeing gigantic hugepage fixed in commit 55f67141a892 "mm: hugetlb: fix softlockup when a large number of hugepages are freed." can happen in return_unused_surplus_pages(), so let's fix it.
