Merge tag 'tsm-for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm

Pull trusted security manager (TSM) updates from Dan Williams:

 - Add a general sysfs scheme for publishing "Measurement" values
   provided by the architecture's TEE Security Manager. Use it to
   publish TDX "Runtime Measurement Registers" ("RTMRs") that either
   maintain a hash of stored values (similar to a TPM PCR) or provide
   statically provisioned data. These measurements are validated by a
   relying party.

 - Reorganize the drivers/virt/coco/ directory for "host" and "guest"
   shared infrastructure.

 - Fix a configfs-tsm-report unregister bug

 - With CONFIG_TSM_MEASUREMENTS joining CONFIG_TSM_REPORTS and in
   anticipation of more shared "TSM" infrastructure arriving, rename the
   maintainer entry to "TRUSTED SECURITY MODULE (TSM) INFRASTRUCTURE".
