I'd like to get Paul's patch into mainline this evening, to give us a
chance to get the subsequent mess sorted out in time for next
linux-next[*].  So there's no rush on this update.

[*] Judging by this:

kernel/cpuset.c: In function 'cpuset_common_file_write':
kernel/cpuset.c:1374: warning: passing argument 3 of 'update_flag' makes integer from pointer without a cast
kernel/cpuset.c: In function 'cpuset_destroy':
kernel/cpuset.c:1793: warning: passing argument 3 of 'update_flag' makes integer from pointer without a cast

Paul should drop sched-devel.  I'm suspecting it contains stale old stuff
which wasn't supposed to be there.
