Pull SELinux updates from Paul Moore:
 "SELinux is back with a quiet pull request for v4.18. Three patches,
  all small: two cleanups of the SELinux audit records, and one to
  migrate to a newly defined type (vm_fault_t).

  Everything passes our test suite, and as of about five minutes ago it
  merged cleanly with your tree"
