Compared with v1 [1], only tags (R/b, S/b) updates, and a typo fix, no code change. This series picks cleanup from my previous kvmclock [2] (as other renaming attempts were temporarily put on hold). In addition, this series also include the cleanup on a historically workaround and recent comment of coco interface [3]. Avoiding the fragmentation of these misc cleanups, I consolidated them all in one series and was able to tackle them in one go!
