  selftests/powerpc: Adjust wild_bctr to build with old binutils (2018-11-15 23:05:17 +1100)

- ------------------------------------------------------------------
powerpc fixes for 4.20 #3

Two weeks worth of fixes since rc1.

 - I broke 16-byte alignment of the stack when we moved PPR into pt_regs.
   Despite being required by the ABI this broke almost nothing, we eventually
   hit it in code where GCC does arithmetic on the stack pointer assuming the
   bottom 4 bits are clear. Fix it by padding the in-kernel pt_regs by 8 bytes.

 - A couple of commits fixing minor bugs in the recent SLB rewrite.

 - A build fix related to tracepoints in KVM in some configurations.

 - Our old "IO workarounds" code written for Cell couldn't coexist in a kernel
   that runs on Power9 with the Radix MMU, fix that.

 - Remove the NPU DMA ops, these just printed a warning and should never have
   been called.

 - Suppress an overly chatty message triggered by CPU hotplug in some configs.

 - Two small selftest fixes.

Thanks to:
  Alistair Popple, Gustavo Romero, Nicholas Piggin, Satheesh Rajendran, Scott Wood.
