Merge branch 'upstream' of git://git.infradead.org/users/pcmoore/audit

Pull audit updates from Paul Moore:
 "Seven audit patches for 4.5, all very minor despite the diffstat.

  The diffstat churn for linux/audit.h can be attributed to needing to
  reshuffle the linux/audit.h header to fix the seccomp auditing issue
  (see the commit description for details).

  Besides the seccomp/audit fix, most of the fixes are around trying to
  improve the connection with the audit daemon and a Kconfig
  simplification.  Nothing crazy, and everything passes our little
  audit-testsuite"

* 'upstream' of git://git.infradead.org/users/pcmoore/audit:
  audit: always enable syscall auditing when supported and audit is enabled
  audit: force seccomp event logging to honor the audit_enabled flag
  audit: Delete unnecessary checks before two function calls
  audit: wake up threads if queue switched from limited to unlimited
  audit: include auditd's threads in audit_log_start() wait exception
  audit: remove audit_backlog_wait_overflow
  audit: don't needlessly reset valid wait time
