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

Hi Rusty,

Today's linux-next merge of the rr tree got a conflict in
arch/x86/kernel/cpu/cpufreq/powernow-k8.c between commit
df1829770db415dc5a5ed5ada3bd70176c6f0a01 ("[CPUFREQ] powernow-k8 cleanup
msg if BIOS does not export ACPI _PSS cpufreq data") from Linus' tree and
commit acff715b1f07d1e8366f75ef918233db7a849445 ("cpumask: avoid playing
with cpus_allowed in powernow-k8.c") from the rr tree.

Just overlapping additions. I fixed it up (see below) and can carry the
fix for a while.
