Merge tag 'x86_tdx_for_6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull Intel Trust Domain Extensions (TDX) updates from Dave Hansen:
 "Other than a minor fixup, the content here is to ensure that TDX
  guests never see virtualization exceptions (#VE's) that might be
  induced by the untrusted VMM.

  This is a highly desirable property. Without it, #VE exception
  handling would fall somewhere between NMIs, machine checks and total
  insanity. With it, #VE handling remains pretty mundane.

  Summary:

   - Fixup comment typo

   - Prevent unexpected #VE's from:
      - Hosts removing perfectly good guest mappings (SEPT_VE_DISABLE)
      - Excessive #VE notifications (NOTIFY_ENABLES) which are delivered
        via a #VE"
