Disable migration when probing VMX support during module load to ensure the CPU is stable, mostly to match similar SVM logic, where allowing migration effective requires deliberately writing buggy code. As a bonus, KVM won't report the wrong CPU to userspace if VMX is unsupported, but in practice that is a very, very minor bonus as the only way that reporting the wrong CPU would actually matter is if hardware is broken or if the system is misconfigured, i.e. if KVM gets migrated from a CPU that _does_ support VMX to a CPU that does _not_ support VMX.

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.
