Unfortunately it wasn't the only problem. Now we have:

arch/powerpc/kernel/entry_64.S: Assembler messages:
arch/powerpc/kernel/entry_64.S:260: Error: unrecognized opcode: `rfi_to_user'
arch/powerpc/kernel/entry_64.S:270: Error: unrecognized opcode: `rfi_to_kernel'
arch/powerpc/kernel/entry_64.S:885: Error: unrecognized opcode: `rfi_to_user'
arch/powerpc/kernel/entry_64.S:900: Error: unrecognized opcode: `rfi_to_kernel'

Looks like 222f20f140623 ("powerpc/64s: Simple RFI macro conversions") is missing,
or at least part of it. Unfortunately it doesn't apply cleanly.

4.4 also now has a different failure.

In file included from drivers/staging/rdma/ehca/hcp_if.c:45:0:
arch/powerpc/include/asm/hvcall.h:439:2: error: unknown type name 'u64'
  u64 character;
  ^
arch/powerpc/include/asm/hvcall.h:440:2: error: unknown type name 'u64'
  u64 behaviour;

You'll need 1b689a95ce742 to fix that problem.
