Subject: [PATCH v6 0/7] rust/hrtimer: Various hrtimer + time additions

This is a collection of various bindings that I added to hrtimer when I
was originally getting it ready to be used in rvkms. I've mostly been
waiting for Andreas's hrtimer series to go upstream before submitting
these.

All of these are currently being used within rvkms for vblank emulation.

Previous versions:
  Version 1: https://lkml.org/lkml/2025/4/2/1474
  Version 2: https://lkml.org/lkml/2025/4/15/1750
  Version 3 (only a revision of one patch): https://lkml.org/lkml/2025/4/15/1780
  Version 4: https://lkml.org/lkml/2025/4/29/1715
  Version 5: https://lkml.org/lkml/2025/6/13/1785

Usage example:
 (keep in mind, I haven't rebased the example entirely - but the only
  differences there is a few comments)
