Hi James,

Here is the pull request for 4.12.

Major new features have been landed:

1. TPM resource manager. There's a new device called /dev/tpmrm0. When this
device is opened, a new session is created that is isolated from other users.
Each user has its own set of volatile objects. There is also a new internal
structure called struct tpm_space. This structure can be passed to tpm_transmit
function and have own session to interact with the TPM. This could be
potentially utilized by other kernel subsystems in the future.
2. ARM64 for support for tpm_crb.
3. Support for requesting and relinquishing locality 0 in tpm_crb. TXT uses
locality 2 so we cannot assume that locality 0 is readily reserved when used
in combination with TXT.
4. Comprehensive overhaul to tpm_tis_spi by Peter Huewe.
