Linus Torvalds b19239143e Hi,
These are the changes for the TPM driver with a single major new
 feature: TPM bus encryption and integrity protection. The key pair
 on TPM side is generated from so called null random seed per power
 on of the machine [1]. This supports the TPM encryption of the hard
 drive by adding layer of protection against bus interposer attacks.
 
 Other than the pull request a few minor fixes and documentation for
 tpm_tis to clarify basics of TPM localities for future patch review
 discussions (will be extended and refined over times, just a seed).
