Subject: [PATCH 0/6] acpi-cpufreq and powernow-k8 fixes

From: Borislav Petkov <bp@...e.de>

Hi all,

here are a couple of patches fixing acpi-cpufreq and powernow-k8 loading
sequence and handoff.

Patch 0001 should be in Rafael's tree already but I'm adding it here for
the sake of completeness. Basically, we want to address all possible
cases of powernow-k8 and acpi-cpufreq:

(M: module, Y: built-in)

powernow-k8		acpi-cpufreq
M			M		- powernow-k8 requests acpi-cpufreq
M			Y		- powernow-k8 sees already loaded acpi-cpufreq
Y			M		- impossible after patch 0001
Y			Y		- patches 2,3 fix that

Anyway, please take a look and let me know.

Thanks.

  powernow-k8: Add a kconfig dependency on acpi-cpufreq

  cpufreq: Add a get_current_driver helper
  powernow-k8: Cleanup module request
  powernow-k8: Cleanup init function
