VM_ENTRY_IA32E_MODE control is toggled dynamically by vmx_set_efer() and setup_vmcs_config() doesn't check its existence. On the contrary, nested_vmx_setup_ctls_msrs() doesn set it on x86_64. Add the missing check and filter the bit out in vmx_vmentry_ctrl(). No (real) functional change intended as all existing CPUs supporting long mode and VMX are supposed to have it.

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.
