Jérôme Glisse 2c8fc3dcf2 mm/hmm: add ARCH_HAS_HMM_MIRROR ARCH_HAS_HMM_DEVICE Kconfig
Add 2 new Kconfig variables that are not used by anyone.  I check that
various make ARCH=somearch allmodconfig do work and do not complain.  This
new Kconfig needs to be added first so that device drivers that depend on
HMM can be updated.

Once drivers are updated then I can update the HMM Kconfig to depend on
this new Kconfig in a followup patch.

This is about solving Kconfig for HMM given that device driver are
going through their own tree we want to avoid changing them from the mm
tree.  So plan is:

1 - Kernel release N add the new Kconfig to mm/Kconfig (this patch)
2 - Kernel release N+1 update driver to depend on new Kconfig ie
    stop using ARCH_HASH_HMM and start using ARCH_HAS_HMM_MIRROR
    and ARCH_HAS_HMM_DEVICE (one or the other or both depending
    on the driver)
3 - Kernel release N+2 remove ARCH_HASH_HMM and do final Kconfig
    update in mm/Kconfig

README

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.
