Paolo Bonzini 8a1b43922d kvm: vmx: Reinstate support for CPUs without virtual NMI 
This is more or less a revert of commit 2c82878b0c ("KVM: VMX: require
virtual NMI support", 2017-03-27); it turns out that Core 2 Duo machines
only had virtual NMIs in some SKUs.

The revert is not trivial because in the meanwhile there have been several
fixes to nested NMI injection.  Therefore, the entire vNMI state is moved
to struct loaded_vmcs.

Another change compared to before the patch is a simplification here:

       if (unlikely(!cpu_has_virtual_nmis() && vmx->soft_vnmi_blocked &&
           !(is_guest_mode(vcpu) && nested_cpu_has_virtual_nmis(
                                       get_vmcs12(vcpu))))) {

The final condition here is always true (because nested_cpu_has_virtual_nmis
is always false) and is removed.

README 

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.
