+Will and Mark.

Will recently took some stuff for drivers/perf/riscv_* into his 
for-next/perf tree (which I didn't even know about until then, oops), 
but the previous stuff I took through the RISC-V tree.  Always happy to 
get stuff out of my tree, just LMK what you want me to do here.

I did some minor cleanups to the commit text and put them over at 
palmer/riscv-pmu_fixes, it's all passing my tests.  These generally look 
fine to me and they're all stable backports, so no big rush on the merge 
window (which I still have stuff for).
