Binbin Wu 2c49db455e KVM: x86: Add & use kvm_vcpu_is_legal_cr3() to check CR3's legality
Add and use kvm_vcpu_is_legal_cr3() to check CR3's legality to provide
a clear distinction between CR3 and GPA checks.  This will allow exempting
bits from kvm_vcpu_is_legal_cr3() without affecting general GPA checks,
e.g. for upcoming features that will use high bits in CR3 for feature
enabling.

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.
