  ima: digital signature verification using asymmetric keys
  ima: rename hash calculation functions
  ima: use new crypto_shash API instead of old crypto_hash
  ima: add policy support for file system uuid
  evm: add file system uuid to EVM hmac
  tpm_tis: check pnp_acpi_device return code
  char/tpm/tpm_i2c_stm_st33: drop temporary variable for return value
  char/tpm/tpm_i2c_stm_st33: remove dead assignment in tpm_st33_i2c_probe
  char/tpm/tpm_i2c_stm_st33: Remove __devexit attribute
  char/tpm/tpm_i2c_stm_st33: Don't use memcpy for one byte assignment
  tpm_i2c_stm_st33: removed unused variables/code
  TPM: Wait for TPM_ACCESS tpmRegValidSts to go high at startup
  tpm: Fix cancellation of TPM commands (interrupt mode)
  tpm: Fix cancellation of TPM commands (polling mode)
  tpm: Store TPM vendor ID
  TPM: Work around buggy TPMs that block during continue self test
