Add a new ucall hook, GUEST_UCALL_NONE(), to allow tests to make ucalls without allocating a ucall struct, and use it to enable single-step in ARM's debug-exceptions test. Like the disable single-step path, the enabling path also needs to ensure that no exclusive access sequences are attempted after enabling single-step, as the exclusive monitor is cleared on ERET from the debug exception taken to EL2. The test currently "works" because clear_bit() isn't actually an atomic operation... yet.

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 Restructured Text 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.
