Introduce a wrapper around `ktime_t` with a few different useful methods. Rust Binder will use these bindings to compute how many milliseconds a transaction has been active for when dumping the current state of the Binder driver. This replicates the logic in C Binder [1]. For a usage example in Rust Binder, see [2]. ktime_get() cannot be safely called in NMI context. This requirement is not checked by these abstractions, but it is intended that klint [3] or a similar tool will be used to check it in the future.
