  tpm: Add !tpm_amd_is_rng_defective() to the hwrng_unregister() call site (2023-04-24 16:15:53 +0300)

----------------------------------------------------------------
Two major features are included into this pull request. The links for
the landed patch sets are below.

The .machine keyring, used for Machine Owner Keys (MOK), acquired the
ability to store only CA enforced keys, and put rest to the .platform
keyring, thus separating the code signing keys from the keys that are
used to sign certificates. This essentially unlocks the use of the
.machine keyring as a trust anchor for IMA. It is an opt-in feature,
meaning that the additional contraints won't brick anyone who does not
care about them.

The 2nd feature is the enablement of interrupt based transactions with
discrete TPM chips (tpm_tis). There was code for this existing but it
never really worked so I consider this a new feature rather than a bug
fix. Before the driver just falled back to the polling mode.
