Subjectlinux-next: build warning after merge of the akpm-current tree
Hi all,

After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/hugetlbfs/inode.c: In function 'remove_inode_hugepages':
fs/hugetlbfs/inode.c:460:44: warning: 'hash' may be used uninitialized in this function [-Wmaybe-uninitialized]
460 | mutex_unlock(&hugetlb_fault_mutex_table[hash]);
| ^
fs/hugetlbfs/inode.c:463:5: warning: 'index' may be used uninitialized in this function [-Wmaybe-uninitialized]
463 | hugetlb_vmdelete_list(&mapping->i_mmap,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
464 | index * pages_per_huge_page(h),
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
465 | (index + 1) * pages_per_huge_page(h));
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit

6fdc8f8d1781 ("hugetlbfs: use i_mmap_rwsem to address page fault/truncate race")
