mm/hugetlb.c: fix virtual address handling in hugetlb fault
handle_mm_fault() passes 'faulted' address to hugetlb_fault(). This address is not aligned to a hugepage boundary. Most of the functions for hugetlb pages are aware of that and calculate an alignment themselves. However some functions such as copy_user_huge_page() and clear_huge_page() don't handle alignment by themselves. This patch make hugeltb_fault() fix the alignment and pass an aligned addresss (to address of a faulted hugepage) to functions.
