Re: [RFC][PATCH 0/2] Make sparcv8 work again on cas enabled hardware

The CAS for leon userspace uses ASI_USERDATA (0x0A), not the v9 ASI_P
(0x80). It's a really annoying difference that I wish the cpu
designers hadn't made.


I don't think they had much choice in the matter given how the ASIs
are doled out in v9 vs. pre-v9. :-/
I didn't think 0x80 was used for anything else on v8, or leon specifically. AFAICS it could easily have been made an alias for 0x0A internally. 

But oh well, it's done.
