It covered all the issues but one. The version of gcc I have on this
machine complained about the 64-bit constant. I added "ULL" to the end of
it and tat made things compile.
That patch, and then an additional one to enable R12k support in pfmon is
included below.
Unfortunately on the kernel I have pfmon still reports "0" for all
counters. Time to start debugging that.
