[PATCH v4 0/7] rust/hrtimer: Various hrtimer + time additions

[Lyude Paul <lyude@redhat.com>]

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.

This patch series is based off Fujita's patch series "rust: Add IO
polling":
