[Stephen Rothwell]

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]
