Precedence: bulk

Patches 1-3 are cleaning parts of uaccess.h not related
to put_user/get_user
Patch 4 removes some usage of consecutives __get_user
Patches 5 rewrite __patch_instruction to not use uaccess.h internals.
Patches 6-8 switch some parts of code to user_access_begin/end blocks

All patches are independant.

Christophe Leroy (8):
  powerpc/uaccess: Also perform 64 bits copies in unsafe_copy_to_user()
    on ppc32
  powerpc/uaccess: Swap clear_user() and __clear_user()
  powerpc/uaccess: Move copy_mc_xxx() functions down
  powerpc/syscalls: Use sys_old_select() in ppc_select()
  powerpc/lib: Don't use __put_user_asm_goto() outside of uaccess.h
  powerpc/net: Switch csum_and_copy_{to/from}_user to user_access block
  powerpc/futex: Switch to user_access block
  powerpc/ptrace: Convert gpr32_set_common() to user access block
