[PATCH v3 0/3] tpm: Preserve TPM measurement log across kexec (ppc64)

[Stefan Berger]

The of-tree subsystem does not currently preserve the IBM vTPM 1.2 and
vTPM 2.0 measurement logs across a kexec on ppc64. This series fixes this
for the kexec_file_load() syscall using the flattened device tree (fdt) to
carry the measurement log's buffer across kexec.

  tpm: of: Make of-tree specific function commonly available
  of: kexec: Refactor IMA buffer related functions to make them reusable
  tpm/kexec: Duplicate TPM measurement log in of-tree for kexec
