Currently, we simply hang using "while (1) ;" upon any unexpected guest traps because the default guest trap handler is guest_hang(). The above approach is not useful to anyone because KVM selftests users will only see a hung application upon any unexpected guest trap. This patch improves unexpected guest trap handling for KVM RISC-V selftests by doing the following: 1) Return to host user-space 2) Dump VCPU registers 3) Die using TEST_ASSERT(0, ...)

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.
