  Config option to set a default LSM
  sysctl: require CAP_SYS_RAWIO to set mmap_min_addr
  tpm: autoload tpm_tis based on system PnP IDs
  tpm_tis: TPM_STS_DATA_EXPECT workaround
  define convenient securebits masks for prctl users (v2)
  tpm: fix header for modular build
  tomoyo: improve hash bucket dispersion
  tpm add default function definitions
  LSM: imbed ima calls in the security hooks
