-The problem is that base address allocated from hugetlbfs is not aligned
-with pmd size. Here add a checking for hugetlbfs and align base address
-with pmd size. After this patch the test case "testcases/bin/hugefork02"
-passes to run.
-
-This is similar to the commit 7f24cbc9c4d42db8a3c8484d1 ("mm/mmap: teach
-generic_get_unmapped_area{_topdown} to handle hugetlb mappings").
