linux-next: build failure after merge of the akpm-current tree

[Stephen Rothwell]

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

mm/swap_slots.c: In function 'alloc_swap_slot_cache':
mm/swap_slots.c:126:10: error: implicit declaration of function 'kvzalloc' [-Werror=implicit-function-declaration]
  slots = kvzalloc(sizeof(swp_entry_t) * SWAP_SLOTS_CACHE_SIZE,
          ^
mm/swap_slots.c:126:8: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
  slots = kvzalloc(sizeof(swp_entry_t) * SWAP_SLOTS_CACHE_SIZE,
        ^
mm/swap_slots.c:131:12: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
  slots_ret = kvzalloc(sizeof(swp_entry_t) * SWAP_SLOTS_CACHE_SIZE,
            ^

Caused by commit

  22cf2f4616c6 ("mm, swap: U=use kvzalloc to allocate some swap data structure")

The patches adding kvzalloc seem to have vanished :-(

I have reverted that commit for today.
