[PATCH v2 0/6] powerpc: sstep: Extend instruction emulation support

[Sandipan Das <sandipan@linux.ibm.com>]

This series adds emulation support for some additional ISA 3.0
instructions, most of which are now generated by a recent compiler
(e.g. gcc-8.x) when building the kernel with CONFIG_POWER9_CPU=y.

Changelog:
  v1 -> v2:
    - Use a conservative approach when using the multiply-add and
      darn instructions via inline assembly because older binutils
      may not be able to recognize them (as pointed out by Michael).
