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).
