Pull tomoyo updates from Tetsuo Handa:
 "One bugfix patch, one preparation patch, and one conversion patch.

  TOMOYO is useful as an analysis tool for learning how a Linux system
  works. My boss was hoping that SELinux's policy is generated from what
  TOMOYO has observed. A translated paper describing it is available at

    https://master.dl.sourceforge.net/project/tomoyo/docs/nsf2003-en.pdf/nsf2003-en.pdf?viasf=1

  Although that attempt failed due to mapping problem between inode and
  pathname, TOMOYO remains as an access restriction tool due to ability
  to write custom policy by individuals.

  I was delivering pure LKM version of TOMOYO (named AKARI) to users who
  cannot afford rebuilding their distro kernels with TOMOYO enabled. But
  since the LSM framework was converted to static calls, it became more
  difficult to deliver AKARI to such users. Therefore, I decided to
  update TOMOYO so that people can use mostly LKM version of TOMOYO with
  minimal burden for both distributors and users"
