    Pull audit updates from Eric Paris:
     "So this change across a whole bunch of arches really solves one basic
      problem.  We want to audit when seccomp is killing a process.  seccomp
      hooks in before the audit syscall entry code.  audit_syscall_entry
      took as an argument the arch of the given syscall.  Since the arch is
      part of what makes a syscall number meaningful it's an important part
      of the record, but it isn't available when seccomp shoots the
      For most arch's we have a better way to get the arch (syscall_get_arch)
      So the solution was two fold: Implement syscall_get_arch() everywhere
      there is audit which didn't have it.  Use syscall_get_arch() in the
      seccomp audit code.  Having syscall_get_arch() everywhere meant it was
      a useless flag on the stack and we could get rid of it for the typical
      syscall entry.
      The other changes inside the audit system aren't grand, fixed some
      records that had invalid spaces.  Better locking around the task comm
      field.  Removing some dead functions and structs.  Make some things
      static.  Really minor stuff"
