Kai Huang 8acc0993e3 kvm, x86, mmu: Use kernel generic dynamic physical address mask
AMD's SME/SEV is no longer the only case which reduces supported
physical address bits, since Intel introduced Multi-key Total Memory
Encryption (MKTME), which repurposes high bits of physical address as
keyID, thus effectively shrinks supported physical address bits. To
cover both cases (and potential similar future features), kernel MM
introduced generic dynamaic physical address mask instead of hard-coded
__PHYSICAL_MASK in 'commit 94d49eb30e ("x86/mm: Decouple dynamic
__PHYSICAL_MASK from AMD SME")'. KVM should use that too.

Change PT64_BASE_ADDR_MASK to use kernel dynamic physical address mask
when it is enabled, instead of sme_clr. PT64_DIR_BASE_ADDR_MASK is also
deleted since it is not used at all.

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.
