Subject: [PATCH 0/9] powerpc32: set of optimisation of network checksum functions

This patch serie gather patches related to checksum functions on powerpc.
Some of those patches have already been submitted individually.

Christophe Leroy (9):
  powerpc: unexport csum_tcpudp_magic
  powerpc: mark xer clobbered in csum_add()
  powerpc32: checksum_wrappers_64 becomes checksum_wrappers
  powerpc: inline ip_fast_csum()
  powerpc32: rewrite csum_partial_copy_generic() based on
    copy_tofrom_user()
  powerpc32: optimise a few instructions in csum_partial()
  powerpc32: optimise csum_partial() loop
  powerpc: simplify csum_add(a, b) in case a or b is constant 0
  powerpc: optimise csum_partial() call when len is constant
