linux-next: manual merge of the rr tree with the cpufreq-current tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Rusty,

Today's linux-next merge of the rr tree got a conflict in
arch/x86/kernel/cpu/cpufreq/powernow-k8.c between commits
ec50b17b706931fb5d2854893cfa4b3f96f19276 ("[CPUFREQ] reduce scope of
ACPI_PSS_BIOS_BUG_MSG[]") and 97f1bb65966b4276581988755238a1b326fce475
("[CPUFREQ] powernow-k8: get drv data for correct CPU") from the
cpufreq-current tree and commit fd9641cb9b0cd9296a83242164d53517351b6aaa
("cpumask: avoid playing with cpus_allowed in powernow-k8.c") from the rr
tree.

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