Regarding terminology, I think the mismatch is throughout the code right? So many of the existing "softmmu" files and directories should actually be called "system", or "sysemu" to match include/sysemu right? To me these distinctions are a bit unclear. Maybe it would be good to have clear documentation about this in devel/ to use as a reference and end-goal, and then we could do a pass of the whole code to fix the discrepancies in the use of the terms?
