Introduce Rust support for the `hrtimer` subsystem:
- Add a way to use the `hrtimer` subsystem from Rust. Rust code can now set up
intrusive timers without allocating when starting the timer.
- Add support for `Pin<Box<_>>`, `Arc<_>`, `Pin<&_>` and `Pin<&mut _>` as
pointer types for use with timer callbacks.
- Add support for setting clock source and timer mode.
`kernel` crate:
- Add `Arc::as_ptr` for converting an `Arc` to a raw pointer. This is a
dependency for the `hrtimer` API.
- Add `Box::into_pin` for converting a `Box<_>` into a `Pin<Box<_>>` to align
with Rust `alloc`. This is a dependency for the `hrtimer` API.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
