Merge tag 'x86_tdx_for_6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull tdx updates from Dave Hansen:
 "These essentially refine some interactions between TDX guests and
  VMMs.

  The first leverages a new TDX module feature to runtime disable the
  ability for a VM to inject #VE exceptions. Before this feature, there
  was only a static on/off switch and the guest had to panic if it was
  configured in a bad state.

  The second lets the guest opt in to be able to access the topology
  CPUID leaves. Before this, accesses to those leaves would #VE.

  For both of these, it would have been nicest to just change the
  default behavior, but some pesky "other" OSes evidently need to retain
  the legacy behavior.

  Summary:

   - Add new infrastructure for reading TDX metadata

   - Use the newly-available metadata to:
      - Disable potentially nasty #VE exceptions
      - Get more complete CPU topology information from the VMM"
