Binbin Wu 3963c52df4 KVM: x86: Add an emulation flag for implicit system access
Add an emulation flag X86EMUL_F_IMPLICIT to identify implicit system access
in instruction emulation.  Don't bother wiring up any usage at this point,
as Linear Address Space Separation (LASS) will be the first "real" consumer
of the flag and LASS support will require dedicated hooks, i.e. there
aren't any existing calls where passing X86EMUL_F_IMPLICIT is meaningful.

Add the IMPLICIT flag even though there's no imminent usage so that
Linear Address Masking (LAM) support can reference the flag to document
that addresses for implicit accesses aren't untagged.

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.
