Subject: linux-next: manual merge of the tip tree with the cputime tree

Hi all,

Today's linux-next merge of the tip tree got a conflict in
fs/proc/uptime.c between commit c3e0ef9a298e ("[S390] fix cputime
overflow in uptime_proc_show") from the cputime tree and commit
3292beb340c7 ("sched/accounting: Change cpustat fields to an array") from
the tip tree.

I fixed it up (I think - see below) and can carry the fix as necessary.

Generally, you guys seem to be working a little at cross purposes ...
