Pull x86 TDX updates from Dave Hansen:
 "Intel Trust Domain updates.

  The existing TDX code needs a _bit_ of metadata from the TDX module.
  But KVM is going to need a bunch more very shortly. Rework the
  interface with the TDX module to be more consistent and handle the new
  higher volume.

  The TDX module has added a few new features. The first is a promise
  not to clobber RBP under any circumstances. Basically the kernel now
  will refuse to use any modules that don't have this promise. Second,
  enable the new "REDUCE_VE" feature. This ensures that the TDX module
  will not send some silly virtualization exceptions that the guest had
  no good way to handle anyway.

   - Centralize global metadata infrastructure

   - Use new TDX module features for exception suppression and RBP
     clobbering"
