[GIT PULL] x86/tdx for 7.1-rc1

[Dave Hansen <dave.hansen@linux.intel.com>]

Hi Linus,

Please pull some x86/tdx changes for 7.1-rc1.

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.

The GetQuote tweak collides with a fix that showed up around 7.0-rc5.
Ingo resolved the conflict for the tip tree and I've appended it here
in case it is useful to you.
