Subject: linux-next: manual merge of the percpu tree with the s390 tree

Hi all,

Today's linux-next merge of the percpu tree got a conflict in
arch/s390/kernel/vtime.c between commit 4dc0f1e9c0a9 ("s390/idle:
consolidate idle functions and definitions") from the s390 tree and
commit eb7e7d766326 ("s390: Replace __get_cpu_var uses") from the
percpu tree.

I fixed it up (the former moved the code modified by the latter into a
new file, so I just removed the code and added the patch below) and can
carry the fix as necessary (no action is required).
