  MAINTAINERS: Add tomoyo-dev-en ML.
  SELinux: define permissions for DCB netlink messages
  encrypted-keys: style and other cleanup
  encrypted-keys: verify datablob size before converting to binary
  trusted-keys: kzalloc and other cleanup
  trusted-keys: additional TSS return code and other error handling
  syslog: check cap_syslog when dmesg_restrict
  Smack: Transmute labels on specified directories
  selinux: cache sidtab_context_to_sid results
  SELinux: do not compute transition labels on mountpoint labeled filesystems
  This patch adds a new security attribute to Smack called SMACK64EXEC. It defines label that is used while task is running.
  SELinux: merge policydb_index_classes and policydb_index_others
  selinux: convert part of the sym_val_to_name array to use flex_array
  selinux: convert type_val_to_struct to flex_array
  flex_array: fix flex_array_put_ptr macro to be valid C
  SELinux: do not set automatic i_ino in selinuxfs
  selinux: rework security_netlbl_secattr_to_sid
  SELinux: standardize return code handling in selinuxfs.c
  SELinux: standardize return code handling in selinuxfs.c
  SELinux: standardize return code handling in policydb.c
