Subject: [RFC/RFT v4 0/5] Add generic trusted keys framework/subsystem

This patch-set is an outcome of discussion here [1]. It has evolved very
much since v1 to create, consolidate and generalize trusted keys
subsystem.

This framework has been tested with trusted keys support provided via TEE
but I wasn't able to test it with a TPM device as I don't possess one. It
would be really helpful if others could test this patch-set using a TPM
device.

Changes in v4:
1. Separate patch for export of tpm_buf code to include/linux/tpm.h
2. Change TPM1.x trusted keys code to use common tpm_buf
3. Keep module name as trusted.ko only

Changes in v3:

Move TPM2 trusted keys code to trusted keys subsystem.

Changes in v2:

Split trusted keys abstraction patch for ease of review.

Sumit Garg (5):
  tpm: move tpm_buf code to include/linux/
  KEYS: trusted: use common tpm_buf for TPM1.x code
  KEYS: trusted: create trusted keys subsystem
  KEYS: trusted: move tpm2 trusted keys code
  KEYS: trusted: Add generic trusted keys framework
