Merge tag 'x86_tdx_for_7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 TDX updates from Dave Hansen:
 "The only real thing of note here is printing the TDX module version.

  This is a little silly on its own, but the upcoming TDX module update
  code needs the same TDX module call. This shrinks that set a wee bit.

  There's also few minor macro cleanups and a tweak to the GetQuote ABI
  to make it easier for userspace to detect zero-length (failed) quotes"
