[PATCH v5 0/2] enhance TPM 2.0 extend function to support multiple PCR banks

IMA extends its hash measurements in the TPM PCRs, based on policy. The existing in-kernel TPM extend function extends only the SHA1 PCR bank. TPM 2.0 defines multiple PCR banks, to support different hash algorithms. The TCG TPM 2.0 Specification[1] recommends extending all active PCR banks to
