Rework vmx_set_rflags() to avoid the extra code need to handle emulation of real mode and invalid state when unrestricted guest is disabled. The primary reason for doing so is to avoid the call to vmx_get_rflags(), which will incur a VMREAD when RFLAGS is not already available. When running nested VMs, the majority of calls to vmx_set_rflags() will occur without an associated vmx_get_rflags(), i.e. when stuffing GUEST_RFLAGS during transitions between vmcs01 and vmcs02. Note, vmx_get_rflags() guarantees RFLAGS is marked available.

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.
