Hardcode the VMCALL/VMMCALL opcodes in dedicated arrays instead of extracting the opcodes from inline asm, and patch in the "other" opcode so as to preserve the original opcode, i.e. the opcode that the test executes in the guest. Preserving the original opcode (by not patching the source), will make it easier to implement a check that KVM doesn't modify the opcode (the test currently only verifies that a #UD occurred). Use INT3 (0xcc) as the placeholder so that the guest will likely die a horrible death if the test's patching goes awry. As a bonus, patching from within the test dedups a decent chunk of code.

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.
