Merge branch 'work.csum_and_copy' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull copy_and_csum cleanups from Al Viro:
 "Saner calling conventions for csum_and_copy_..._user() and friends"

[ Removing 800+ lines of code and cleaning stuff up is good  - Linus ]

* 'work.csum_and_copy' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  ppc: propagate the calling conventions change down to csum_partial_copy_generic()
  amd64: switch csum_partial_copy_generic() to new calling conventions
  sparc64: propagate the calling convention changes down to __csum_partial_copy_...()
  xtensa: propagate the calling conventions change down into csum_partial_copy_generic()
  mips: propagate the calling convention change down into __csum_partial_copy_..._user()
  mips: __csum_partial_copy_kernel() has no users left
  mips: csum_and_copy_{to,from}_user() are never called under KERNEL_DS
  sparc32: propagate the calling conventions change down to __csum_partial_copy_sparc_generic()
  i386: propagate the calling conventions change down to csum_partial_copy_generic()
  sh: propage the calling conventions change down to csum_partial_copy_generic()
  m68k: get rid of zeroing destination on error in csum_and_copy_from_user()
  arm: propagate the calling convention changes down to csum_partial_copy_from_user()
  alpha: propagate the calling convention changes down to csum_partial_copy.c helpers
  saner calling conventions for csum_and_copy_..._user()
  csum_and_copy_..._user(): pass 0xffffffff instead of 0 as initial sum
  csum_partial_copy_nocheck(): drop the last argument
  unify generic instances of csum_partial_copy_nocheck()
  icmp_push_reply(): reorder adding the checksum up
  skb_copy_and_csum_bits(): don't bother with the last argument
