When emulating vCPU INIT, do not unconditionally refresh the list of user return MSRs that need to be loaded into hardware when running the guest. Unconditionally refreshing the list is confusing, as the vast majority of MSRs are not modified on INIT. The real motivation is to handle the case where an INIT during long mode obviates the need to load the SYSCALL MSRs, and that is handled as needed by vmx_set_efer().

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.
