Hi Linus,

Please pull some x86/tdx changes for v6.2.

This includes a single chunk of new functionality for TDX guests
which allows them to talk to the trusted TDX module software and
obtain an attestation report.  This report can then be used to
prove the trustworthiness of the guest to a third party and get
access to things like storage encryption keys.
