Merge tag 'rust-timekeeping-for-v7.1' of https://github.com/Rust-for-Linux/linux into rust-next

Pull timekeeping updates from Andreas Hindborg:

 - Expand the example section in the 'HrTimer' documentation.

 - Mark the 'ClockSource' trait as unsafe to ensure valid values for
   'ktime_get()'.

 - Add 'Delta::from_nanos()'.

This is a back merge since the pull request has a newer base -- we will
avoid that in the future.

And, given it is a back merge, it happens to resolve the "subtle" conflict
around '--remap-path-{prefix,scope}' that I discussed in linux-next [1],
plus a few other common conflicts. The result matches what we did for
next-20260407.

The actual diffstat (i.e. using a temporary merge of upstream first) is:
