It is not obvious to my eye how to break up S1NSE0 -- 'NS' is buried in the middle. It might be different if these names were architectural, as if the AT names, but they're not. I think it is clearer to reserve 'S' for 'Secure', and use it consistently. E.g. not the current "S1E3" (stage 1 e3), but "SE3" (secure e3). I think it is clearer to simply document that, unless "Stage" is present in the name, the tlb contains the complete translation. This makes "S12" redundant off of "NSE0", and "S1" off of "E3". We'll still need a renaming of with SecEL2, since "SE0" is no longer complete; we will need to specify "Secure EL1&0" vs "Secure EL2&0". Thus perhaps "SEL10_0" to match the "EL10_0" name that I'm using in this series. r~
