[GIT PULL] Confidential Computing: Attestation fixes for 7.0-rc6

[Dan Williams]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm tags/tsm-fixes-7.0-rc6

...to receive a fix for the tdx-guest driver. It has appeared in linux-next and
collides with a fix coming from tip/x86/tdx (resolution below). Going forward
all tdx-guest updates should move to the tip/x86/tdx topic, and tsm.git can
remain focused on core attestation report infrastructure.

My conflict resolution matches linux-next's:
