      Pull vfs fixes from Al Viro.
      
       - fix io_destroy()/aio_complete() race
      
       - the vfs_open() change to get rid of open_check_o_direct() boilerplate
         was nice, but buggy. Al has a patch avoiding a revert, but that's
         definitely not a last-day fodder, so for now revert it is...

      This reverts commit cab64df1.
      
      Having vfs_open() in some cases drop the reference to
      struct file combined with
      
      	error = vfs_open(path, f, cred);
      	if (error) {
      		put_filp(f);
      		return ERR_PTR(error);
      	}
      	return f;
      
      is flat-out wrong.  It used to be
      
      		error = vfs_open(path, f, cred);
      		if (!error) {
      			/* from now on we need fput() to dispose of f */
      			error = open_check_o_direct(f);
      			if (error) {
      				fput(f);
      				f = ERR_PTR(error);
      			}
      		} else {
      			put_filp(f);
      			f = ERR_PTR(error);
      		}
      
      and sure, having that open_check_o_direct() boilerplate gotten rid of is
      nice, but not that way...
      
      Worse, another call chain (via finish_open()) is FUBAR now wrt
      FILE_OPENED handling - in that case we get error returned, with file
      already hit by fput() *AND* FILE_OPENED not set.  Guess what happens in
      path_openat(), when it hits
      
      	if (!(opened & FILE_OPENED)) {
      		BUG_ON(!error);
      		put_filp(file);
      	}
      
      The root cause of all that crap is that the callers of do_dentry_open()
      have no way to tell which way did it fail; while that could be fixed up
      (by passing something like int *opened to do_dentry_open() and have it
      marked if we'd called ->open()), it's probably much too late in the
      cycle to do so right now.

      Pull scheduler fixes from Thomas Gleixner:
      
       - two patches addressing the problem that the scheduler allows under
         certain conditions user space tasks to be scheduled on CPUs which are
         not yet fully booted which causes a few subtle and hard to debug
         issue
      
       - add a missing runqueue clock update in the deadline scheduler which
         triggers a warning under certain circumstances
      
       - fix a silly typo in the scheduler header file
