Maybe just "combine". Or better yet, "unify". Ok, I have edited all the changelogs accordingly (and also flipped around the 'clock MONOTONIC' language to the more readable 'the MONOTONIC clock' variant), the resulting titles are (in order): 72199320d49d: timekeeping: Add the new CLOCK_MONOTONIC_ACTIVE clock d6ed449afdb3: timekeeping: Make the MONOTONIC clock behave like the BOOTTIME clock f2d6fdbfd238: Input: Evdev - unify MONOTONIC and BOOTTIME clock behavior d6c7270e913d: timekeeping: Remove boot time specific code 7250a4047aa6: posix-timers: Unify MONOTONIC and BOOTTIME clock behavior 127bfa5f4342: hrtimer: Unify MONOTONIC and BOOTTIME clock behavior 92af4dcb4e1c: tracing: Unify the "boot" and "mono" tracing clocks I'll push these out after testing.
