Drop ucall_uninit() and ucall_arch_uninit() now that ARM doesn't modify the host's copy of ucall_exit_mmio_addr, i.e. now that there's no need to reset the pointer before potentially creating a new VM. The few calls to ucall_uninit() are all immediately followed by kvm_vm_free(), and that is likely always going to hold true, i.e. it's extremely unlikely a test will want to effectively disable ucall in the middle of a test.

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.
