Hard-code the flds instruction and assert the exact instruction bytes are present in run->emulation_failure. The test already requires the instruction bytes to be present because that's the only way the test will advance the RIP past the flds and get to GUEST_DONE(). Note that KVM does not necessarily return exactly 2 bytes in run->emulation_failure since it may not know the exact instruction length in all cases. So just assert that run->emulation_failure.insn_size is at least 2.

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.
