This is a next version to RFC patch:
  https://lkml.org/lkml/2018/5/16/36

kbuild test robot reported the following build failure with RFC.

   error: unused variable 'type' [-Werror=unused-variable]
     int type;
         ^~~~

I've fixed it along with following changes.

1st patch introduces a new macro to simplify code a bit.
2nd patch fixes the kernel crash when VSX is not supported
    or disabled.
3rd patch fixes emulate_step() tests

  powerpc/sstep: Fix emulate_step test if VSX not present
