[GIT PULL] Confidential Computing: Attestation Updates for 7.0

[dan.j.williams]

Hi Linus, please pull from:

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

...to receive a couple updates to the maximum buffer sizes supported for
the configfs-tsm-reports interface. Recall this interface is a common
transport that conveys the varied architecture specific launch
attestation reports for confidential VMs. 

They have appeared in linux-next with no known reports.
