Don't propagate GUEST_SYSENTER_* from vmcs02 to vmcs12 on nested VM-Exit as the vmcs12 fields are updated in vmx_set_msr(), and writes to the corresponding MSRs are always intercepted by KVM when running L2. Dropping the propagation was intended to be done in the same commit that added vmcs12 writes in vmx_set_msr()[1], but for reasons unknown was only shuffled around[2][3].

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.
