Merge branch 'akpm' (fixes from Andrew) 

Merge misc fixes from Andrew Morton:

 - A bunch of fixes

 - Finish off the idr API conversions before someone starts to use the
   old interfaces again.

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  idr: idr_alloc() shouldn't trigger lowmem warning when preloaded
  UAPI: fix endianness conditionals in M32R's asm/stat.h
  UAPI: fix endianness conditionals in linux/raid/md_p.h
  UAPI: fix endianness conditionals in linux/acct.h
  UAPI: fix endianness conditionals in linux/aio_abi.h
  decompressors: fix typo "POWERPC"
  mm/fremap.c: fix oops on error path
  idr: deprecate idr_pre_get() and idr_get_new[_above]()
  tidspbridge: convert to idr_alloc()
  zcache: convert to idr_alloc()
  mlx4: remove leftover idr_pre_get() call
  workqueue: convert to idr_alloc()
  nfsd: convert to idr_alloc()
  nfsd: remove unused get_new_stid()
  kernel/signal.c: use __ARCH_HAS_SA_RESTORER instead of SA_RESTORER
  signal: always clear sa_restorer on execve
  mm: remove_memory(): fix end_pfn setting
  include/linux/res_counter.h needs errno.h
