Support `MITIGATION_SLS` by enabling the target features that Clang does.
Without this, `objtool` would complain if enabled for Rust, e.g.:
rust/core.o: warning: objtool:
_R...next_up+0x44: missing int3 after ret
These should be eventually enabled via `-Ctarget-feature` when `rustc`
starts recognizing them (or via a new dedicated flag) [1].

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.
