linux-next: build failure after merge of the final tree(device-mapper tree related)

[Stephen Rothwell]

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/md/dm-cache-policy-hints.c: In function 'alloc_hash':
drivers/md/dm-cache-policy-hints.c:94:2: error: implicit declaration of function 'vzalloc' [-Werror=implicit-function-declaration]
  hash->table = vzalloc(sizeof(*hash->table) * hash->nr_buckets);
  ^
drivers/md/dm-cache-policy-hints.c:94:14: warning: assignment makes pointer from integer without a cast [enabled by default]
  hash->table = vzalloc(sizeof(*hash->table) * hash->nr_buckets);
              ^
drivers/md/dm-cache-policy-hints.c: In function 'free_hash':
drivers/md/dm-cache-policy-hints.c:101:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]
  vfree(hash->table);
  ^
drivers/md/dm-cache-policy-hints.c: In function 'alloc_bitset':
drivers/md/dm-cache-policy-hints.c:184:2: warning: return makes pointer from integer without a cast [enabled by default]
  return vzalloc(sizeof(unsigned long) * bit_set_nr_words(nr_cblocks));
  ^

Caused by commit ce567d11e819 ("dm cache: add hints policy") from the
device-mapper tree.

I have just left this broken for today.
