FWICS (so far) system resume still works here with the commits between d6ed449afdb3 (timekeeping: Make the MONOTONIC clock behave like the BOOTTIME clock) and 127bfa5f4342 (hrtimer: Unify MONOTONIC and BOOTTIME clock behavior) inclusive reverted on top of 4.17-rc2. [I probably should revert commit 92af4dcb4e1c (tracing: Unify the "boot" and "mono" tracing clocks) too, but it doesn't revert cleanly and it doesn't apprear to affect things here too.]
