Tweak the code and comment that deals with concurrent NMIs to explicitly call out that x86 allows exactly one pending NMI, but that KVM needs to temporarily allow two pending NMIs in order to workaround the fact that the target vCPU cannot immediately recognize an incoming NMI, unlike bare metal. No functional change intended.

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.
