Terry TrittonandGreg Kroah-Hartman 0b34dca1bf selftests/mm: uffd-unit-test check if huge page size is 0 ...

commit 7efa6f2c80 upstream.

If HUGETLBFS is not enabled then the default_huge_page_size function will
return 0 and cause a divide by 0 error. Add a check to see if the huge page
size is 0 and skip the hugetlb tests if it is.
