   xen/cpufreq: Disable the cpu frequency scaling drivers from loading. 
(2012-04-23 20:49:25 -0600)

----------------------------------------------------------------
Bastian Blank (1):
       xen: Add privcmd device driver

Konrad Rzeszutek Wilk (6):
       provide disable_cpufreq() function to disable the API.
       xen/acpi-processor: C and P-state driver that uploads said data 
to hypervisor.
       xen/acpi-processor: Do not depend on CPU frequency scaling drivers.
       xen/acpi: Fix Kconfig dependency on CPU_FREQ
       xen/acpi: Remove the WARN's as they just create noise.
       xen/cpufreq: Disable the cpu frequency scaling drivers from loading.

I will have a look. When all goes well I would probably change the order of
patches to have any config changes after the code changes. But that is minor and
testing may find whether m or y would be a better path anyway...

I put the config changes before the Kconfig patch so that a bisect
will not get caught up in asking for config input from the user. Its
completely benign.
