Wanpeng Li 8ad8182e93 KVM: VMX: Don't expose unrestricted_guest is enabled if ept is disabled
SDM mentioned:

 "If either the “unrestricted guest†VM-execution control or the “mode-based
  execute control for EPT†VM- execution control is 1, the “enable EPTâ€
  VM-execution control must also be 1."

However, we can still observe unrestricted_guest is Y after inserting the kvm-intel.ko
w/ ept=N. It depends on later starts a guest in order that the function
vmx_compute_secondary_exec_control() can be executed, then both the module parameter
and exec control fields will be amended.

This patch fixes it by amending module parameter immediately during vmcs data setup.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
