Merge tag 'x86_misc_for_6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull misc x86 updates from Dave Hansen:
 "The most significant are some changes to ensure that symbols exported
  for KVM are used only by KVM modules themselves, along with some
  related cleanups.

  In true x86/misc fashion, the other patch is completely unrelated and
  just enhances an existing pr_warn() to make it clear to users how they
  have tainted their kernel when something is mucking with MSRs.

  Summary:

   - Make MSR-induced taint easier for users to track down

   - Restrict KVM-specific exports to KVM itself"

* tag 'x86_misc_for_6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86: Restrict KVM-induced symbol exports to KVM modules where obvious/possible
  x86/mm: Drop unnecessary export of "ptdump_walk_pgd_level_debugfs"

  x86/bugs: Drop unnecessary export of "x86_spec_ctrl_base"
  x86/msr: Add CPU_OUT_OF_SPEC taint name to "unrecognized" pr_warn(msg)

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 reStructuredText 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.
