#     
#     Pull SELinux update from Paul Moore:
#      "This is one of the bigger SELinux pull requests in recent years with
#       28 patches. Everything is passing our test suite and the highlights
#       are below:
#     
#        - Mark CONFIG_SECURITY_SELINUX_DISABLE as deprecated. We're some time
#          away from actually attempting to remove this in the kernel, but the
#          only distro we know that still uses it (Fedora) is working on
#          moving away from this so we want to at least let people know we are
#          planning to remove it.
#     
#        - Reorder the SELinux hooks to help prevent bad things when SELinux
#          is disabled at runtime. The proper fix is to remove the
#          CONFIG_SECURITY_SELINUX_DISABLE functionality (see above) and just
#          take care of it at boot time (e.g. "selinux=0").
#     
#        - Add SELinux controls for the kernel lockdown functionality,
#          introducing a new SELinux class/permissions: "lockdown { integrity
#          confidentiality }".
#     
#        - Add a SELinux control for move_mount(2) that reuses the "file {
#          mounton }" permission.
#     
#        - Improvements to the SELinux security label data store lookup
#          functions to speed up translations between our internal label
#          representations and the visible string labels (both directions).
#     
#        - Revisit a previous fix related to SELinux inode auditing and
#          permission caching and do it correctly this time.
#     
#        - Fix the SELinux access decision cache to cleanup properly on error.
#          In some extreme cases this could limit the cache size and result in
#          a decrease in performance.
#     
#        - Enable SELinux per-file labeling for binderfs.
#     
#        - The SELinux initialized and disabled flags were wrapped with
#          accessors to ensure they are accessed correctly.
#     
#        - Mark several key SELinux structures with __randomize_layout.
#     
#        - Changes to the LSM build configuration to only build
#          security/lsm_audit.c when needed.
#     
#        - Changes to the SELinux build configuration to only build the IB
#          object cache when CONFIG_SECURITY_INFINIBAND is enabled.
#     
#        - Move a number of single-caller functions into their callers.
#     
#        - Documentation fixes (/selinux -> /sys/fs/selinux).
#     
#        - A handful of cleanup patches that aren't worth mentioning on their
#          own, the individual descriptions have plenty of detail"
