[v6,0/4] Create and consolidate trusted keys subsystem

Message

This patch-set does restructuring of trusted keys code to create and
consolidate trusted keys subsystem.

Also, patch #2 replaces tpm1_buf code used in security/keys/trusted.c and
crypto/asymmertic_keys/asym_tpm.c files to use the common tpm_buf code.

Changes in v6:
1. Switch TPM asymmetric code also to use common tpm_buf code. These
   changes required patches #1 and #2 update, so I have dropped review
   tags from those patches.
2. Incorporated miscellaneous comments from Jarkko.

Changes in v5:
1. Drop 5/5 patch as its more relavant along with TEE patch-set.
2. Add Reviewed-by tag for patch #2.
3. Fix build failure when "CONFIG_HEADER_TEST" and
   "CONFIG_KERNEL_HEADER_TEST" config options are enabled.
4. Misc changes to rename files.

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 (4):
  tpm: Move tpm_buf code to include/linux/
  KEYS: Use common tpm_buf for trusted and asymmetric keys
  KEYS: trusted: Create trusted keys subsystem
  KEYS: trusted: Move TPM2 trusted keys code
