Sean Christopherson 3b77daa5ef KVM: x86/mmu: WARN on any reserved SPTE value when making a valid SPTE
Replace make_spte()'s WARN on a collision with the magic MMIO value with
a generic WARN on reserved bits being set (including EPT's reserved WX
combination).  Warning on any reserved bits covers MMIO, A/D tracking
bits with PAE paging, and in theory any future goofs that are introduced.

Opportunistically convert to ONCE behavior to avoid spamming the kernel
log, odds are very good that if KVM screws up one SPTE, it will botch all
SPTEs for the same MMU.

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.
