Subject: linux-next: manual merge of the rcu tree with Linus' tree

Hi Paul,

Today's linux-next merge of the rcu tree got a conflict in
arch/x86/kernel/process_64.c between commit a0bfa1373859 ("cpuidle: stop
depending on pm_idle") from Linus' tree and commit 18349ca4b42e ("x86:
Enter rcu extended qs after idle notifier call") from the rcu tree.

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

Cheers,
