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

Hi all,

Today's linux-next merge of the tip tree got a conflict in
drivers/acpi/processor_idle.c between commit 6cb85b2b9df9 ("ACPI /
cpuidle: fix max idle state handling with hotplug CPU support") from the
pm tree and commit 16824255394f ("x86, acpi, idle: Restructure the mwait
idle routines") from the tip tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
