Merge tag 'rust-timekeeping-for-v6.16-v2' of https://github.com/Rust-for-Linux/linux into rust-next

Pull timekeeping updates from Andreas Hindborg:

 - Morph the Rust hrtimer subsystem into the Rust timekeeping subsystem,
   covering delay, sleep, timekeeping, timers. This new subsystem has
   all the relevant timekeeping C maintainers listed in the entry.

 - Replace 'Ktime' with 'Delta' and 'Instant' types to represent a
   duration of time and a point in time.

 - Temporarily add 'Ktime' to 'hrtimer' module to allow 'hrtimer' to
   delay converting to 'Instant' and 'Delta'.
