Since my changes for removing xandespmu haven't landed here yet I think you should keep RISCV_ISA_EXT_XANDESPMU in the diff here and make RISCV_ISA_EXT_ZIMOP have a key of 75. Palmer can probably resolve the conflicting keys when these two series are merged.

I missed that other patches in this series were based off my xtheadvector changes. It's not in the cover letter that there is a dependency though. What do you need from that series for this series to work?
Hey Charlie, I'm not based directly on any of your series, but on riscv/for-next which probably already contains your patches.
Clément
There was some churn here so I didn't expect those to be merged, it looks like a subset of the patches were added to riscv/for-next, sorry for the confusion!
